I bought a set of rims and one of them was painted black. Is there a way to strip the paint off and not damage the clearcoat?

if they're alloy there is no clear.

If it has been painted with a single stage black with no clear coat over it...you could try some paint thinner on a rag and see if it wipes off.

If there is the original clear coat under the black, it may need buffing back to a shine. Usually the original paint or clear coat gets a surface keyed up (sanded) to create a rough surface for the new paint to stick to.

Those rims look good in matte black, ever consider evening them all out black?

I used paint stripper, and a rubber scrapper. Then had a buddy send my rims through the sand blaster with glass beads. It turned out as if the rims were brand new again. I'm just waiting for my powder coating gun. Planning on painting it silver gloss so it looks factory again.
