AR charging handle?

[CZ-75BD]

I'm new to AR platform and wondering about charging handle interchangeability.
I have OLY 9mm AR and want to know if I can use different charging handle from 5.56 or 7.62x39
Thank you

The only difference is between 5.56-length AR15/M16 guns and 7.62-length AR10/SR25. And in that case the only difference is length.
