Can you suffocate/drown a troll?
Can you suffocate/drown the tarrasque?
Yes to 1, no to 2.
Regeneration doesn't cover suffocation/drowning/starvation natively so a troll dies to that. The Tarrasque says nothing shuts down its regen and even if you want to start arguing in language minutae it additionally has a caveat that if placed in an inhospitable region it'll go into stasis which is explicitly immune to those.
I'd say yes to both.
There's no wording on the bestiary that stating that she enters stasis when placed on a inhospitable region, and I don't recall reading that sentence anywhere else, unless it's from a specific campaign world.
The catch on the tarrasque is... her regeneration stays active even with the creature dead. This means, 3 rounds after being suffocated or drowned will return to life at 1HP, regaining consciousnes.
Actually, a very decent way to deal with a Tarrasque is porting her to the air or water planes (as hinted in her regen ability). She cannot fly so in the Plane of Air she'll be stuck in what would be an endless fall, and she cannot breathe underwater so she'd be stuck in a drowning cycle.
The problem with the Tarrasque isn't killing it, it's keeping it dead (which is literally impossible).
So sure, you can drown both. The troll will actually die, the Tarrasque will die and come back to life.
As for imprisoning the Tarrasque on one of the elemental planes...I'm sure that's been tried. And the some crazy worshiper of Rovagug goes and frees their master's favorite pet.

Actuualy, after posting the question here, I was able to found something.
The tarrasque from Inner Sea Gods (but not the one from [Biestiary[/i]) has subtype "spawn of Rovagug". Among other thing it means that it means that it has hibernation ability:
Hibernation (Ex) Spawn of Rovagug can sleep for years, decades, or even centuries and do not need to eat or breathe during these periods of dormancy. If a spawn of Rovagug is forced into an environment where it cannot breathe and would suffocate, it goes into hibernation until conditions are right for it to reawaken. While in hibernation, a spawn of Rovagug’s damage reduction improves to 50/epic and it gains immunity to any spell or spell-like ability that allows spell resistance as well as all divination effects.
So it won't be an endless drowning cycle, the tarrasque will just go into hibernation. That's even better because it won't be regaining consciousness until it can breathe again. So, technically, you could throw the tarrasque in a huge aquarium, and as long as you are able to stop it from destroying it until it goes into hibernation, afterwards you could hold it inside indefinitely, and put it on display.
What is dead may never die, the dread Cthulhu Tarrasque will rise again!

The ability is inherent in the Spawn of Divine Destruction subtype.
Spawn of Divine Destruction can sleep for years, decades, or even centuries and do not need to eat or breathe during these periods of dormancy, though they breathe normally and eat ravenously and almost constantly once they’ve been awakened. If a spawn is forced into an environment where it cannot breathe and would suffocate, it goes into hibernation until conditions are right for it to reawaken.
While in hibernation, a spawn’s damage reduction improves to 50/epic and it gains immunity to any spell or spell-like ability that allows spell resistance as well as all divination effects.

I keep forgetting the SRD changes the names.

Good catch, found her on page 304 of ISG. Still, the subtype is granted on a specific campaign setting so you'd only apply the spawn subtype when playing under that setting, same as specific spells, classes or abilities. Of course, your GM may chose to enforce specific parts of the setting and not the entire book.
Your "everyday" Tarrasque would "just" be the Colossal magical Beast we all know and hate love from the Beatiary or the official SRD.

... or a pissed Marid sending her back along with a "Don't dump sh!t in our plane" note attached...
