Can't say for that specific hardware but it's been done for others. Ms. Pac is probably one of the more famous examples. DK3 is probably another. I can't find a manual for it but 8t looks like it's shared hardware. Hard to say.
Without the manual or schematics, I'd poke around the MAME source for that specific game and see what I can deduce from it. I'd use it as a dev platform as well to save ROM burns.
