anyway to remove a bad spraypaint job that's peeling in spots

[Bellsouth Ijit 2.0]

without destroying the original powdercoat underneath?

I've found a '70s Schwinn Scrambler BMX that someone for some godforsaken
reason spraycan painted it flat red, and is now flaking in spots. The
original paint is a very agreeable glossy candy apple powdercoat. Would
love to be able to strip the spraycan job and somehow salvage the original
paint if at all possible.

Nothing is guaranteed foolproof, safe and effective, but here's where
I would start:

Check with the places that carry professional office and industrial
janitorial supplies; you're looking for "spray graffiti remover". You
will need to be a bit careful with it, or you'll end up dulling the
gloss on the powdercoat, but it's probably your best bet.
Alternately, a strong butyl-based cleaner applied full strength would
probably curdle the paint without doing much to the powdercoat. (Note
the "probably"; butyl-based cleaners are *very* aggressive.)

It would be wise to test both of these on an inconspicuous small part
of the powdercoat before trying them on the rest of the frame.
Depending on the powdercoat and the cleaning material, it might dull
the coating or worse.

without destroying the original powdercoat underneath?.

You could try a rubbing compound as used for F/G boats, or a chrome polishing agent. With a bit of careful skill and determination you might be able to buff the offending topcoat away without doing damage to the layers underneath.

Possibly it was over-painted by someone who stole it.

I fix this one time when they stole my sons BMX bike . They painted it flat
black I just used gas and some elbow grease and it came off. I would soak a
rag wrap the section I was cleaning let it sit for a Little while and it
came off. The bike looked good after.

Spray paint applied over a hard glossy finish is not well bonded, and should
come off easily. The fact that it is peeling supports this. I suggest a
combination of two methods suggested above: 1.) Use a solvent, like
graffiti remover, to get as much as possible without dulling the powder
coat. Then clean up with rubbing compound or polish, to take off the
remaining residue, at the same time creating a sparkling new surface.
