Sure, that's fine.

Just don't break it in the middle of a macro.
If you do, you can't use the -k# debugging option.

And PBP tries to return to BANK0 on each ASM statement.
If you aren't using PREV_BANK or PBP macros, then it won't know the bank has been changed and won't do anything.
But it sounds like you probably aren't changing banks anyway
