You can't just go by dictionary definitions here; usage is more subtle and complicated. As far as official titles go, these mostly just show the sexism built into the language: an emperor is a male ruler, but an empress could be a female ruler or the consort of the ruler. But the male consort of a female ruler would not be called king or emperor. The titles are not equal. And this doesn't even take into account that sometimes women gain a traditionally male title and don't use the female version of it. (Take, for instance, the case of "King Peggy": Peggielene Bartels - Wikipedia.)
I do not take Okrand's use of "emperor" for voDleH and ta' to necessarily mean that these words only refer to men. Sexism is often unconscious and culturally driven, and I would find it perfectly plausible to hear that Okrand simply hadn't considered women when he gave us voDleH, and that the word is gender-neutral. On the other hand, if it does only refer to men, then the sexism is in leaving the female version out of the dictionary.
So don't take these dictionary definitions as clear evidence for
what's happening in Klingon. This is the sort of thing that needs
the Word of Okrand to clarify.
