Rather than risk killing the whole plant if you're not sure, get a razor blade and split the rhizome into two plants - leave the first where it is, and move the second. Should give you a good idea without risking total loss.
I think you are thinking of crypts. I've grown many types of anubias from submersed to emersed and never once have they lost leaves. Crypts on the other hand lose their more delicate submersed leaves for stronger emmersed foliage.
