i would check for cracks. If it's not cracked, or big chunks taken out, I would suppose you could.

C'mon son. that skirt prolly isn't even round anymore. I would be scared to **** using a piston if somebody dropped it on the floor, let alone even thinking about the one you pictured.

Check balance, check for sharp edges, check thickness (those dents under the centre somewhat concern me, as does the fact some of the dents seem to affect the outside of the skirt)... the flame front doesn't care what's under it as long as it holds up. That being said, check the replacement price on a single piston. Might be worth the peace of mind.

Might also consider grams (weight) difference when spinning at high RPM.
