Yes, it does. Different *canonical* units always mean different standard names in the CF standard name table. That is, the identification of the quantity does not depend on the units. However, any units which are have the same physical dimensions as the canonical units are acceptable. For definition of standard names, it doesn't matter whether W or mW are used as canonical units, for example.
