I couldn't find anything that provides a specific origin. It's possible, but somewhat unlikely based on what we can piece together.
Akatas hitch rides on comets; Bestiary 2 suggests that's because they come from a planet that's been destroyed. (I say suggests because the Bestiaries aren't necessarily canon sources for Golarion, as they're setting-neutral.) Though technically, there's nothing saying they are (or aren't) related to the planet where the Silver Mount originated.
Having said that, Androffans were curious folk—that's why they launched the Divinity with habitat pods to carry alien species. Iron Gods intentionally doesn't expose every piece of the crashed ship, and akatas can hibernate indefinitely; if you want to say they brought akatas with them and the akatas survived the crash, it wouldn't be unlikely.
