Yes, that's possible, assuming that one of the sidechains is rotameric and the other isn't. The rotamer will only be changed, though, if it's an improved fit to the map.

One possibility here is that the sidechains forming crystal contacts
are in non-rotameric conformations - in this case, wouldn't the
rotamer correction try to adjust them to agree with other chains?
