Depends on what you're using the rope for. If you're burning the rope for some reason, you can't do that with chain, but you could climb a chain as if it were a rope. It's harder to tie a knot in a chain than in a rope. If you're trying to restrain a creature, you need shackles or manacles (there are rules for them).
This is what GMs are for, to make rulings like this on the fly.

Are we talking about climbing here?

Rope Tricks
Rope tricks can be performed with hemp rope or silk rope, or with similar rope-like items at the GM's discretion.Do you think the GM thinks of chains as a rope-like item?
potentially, just odd to only find rules for an item in a feat

'Are' is a form of 'Is'. Or, more specifically, both are forms of the verb 'be'. So to define one is, by extension, to define the other with the only difference being that 'Are' is the 'present indicative plural' and the 'second person singular' while 'Is' is the 'third person singular present indicative'.
