Thank you, Jim Waddick, for inadvertently answering a question which has been bugging me ever since this issue arose. You see, there are really NOT two peonies named Chameleon/chameleon. The Krekler/Klehm hybrid is Paeonia 'Chameleon'. The other entity is Paeonia x chamaeleon Troitsky ex Grossheim. Note the difference in spelling: the garden peony is named with the American spelling Chameleon. The Troitsky ex Grossheim entity is spelled (as you would expect from a non-American) chamaeleon. Until I followed your link to Carsten Burkhardt's site, I only suspected this spelling difference, but it made me very happy to see it confirmed at his site. So really there is no need to change either name because they are not really the same.
