First things first, Koreans refer to their own ethnicity as 한민족 (Hanminjog) where 족 simply means "clan", afaik. The full name of the Republic of Korea is 대한민국 (Daehanmingg); as that reddit post you linked mentioned, 대 simply means "great" (i.e. a 학생 is a student, a 대학생 is a university student, etc.) and 국 means ... probably not exactly "land" (as 약국 is a pharmacy where 약 is "medicine") but is a general term relating to territory with nuances that are probably untranslatable.
Now this send me down a rabbit hole on figuring out where that "han" came from. The english Wikipedia entry lacks citations about its etymology, so I went to the french one which offers a different explanation, arguing it might stem from the title "Khan" (as well as 하늘, "sky", which I kinda doubt). Accepting that I have to bite the sour apple I tried my luck with ko.wikipedia.org and found that they put the etymology either on "Khan" or on the meaning of "central" that 한 can have. They also note that 韓 has been used in both China and Korea in the name of various kingdoms.
Anyhow, I think it is pretty clear that Koreans refer to themselves as Han, but that mustn't mean they see themselves as chinese. Ethnic terms are always politically charged, and a shared etymology does not mean they identify as another. (Circling back to the Franks example, I myself am sandwiched between the Franks from France and the Franks from Bavaria in a near-rhine region that doesn't consider itself "frank", but rather swabian/alemannic.) "Dutch" and "Deutsch" share an etymology, yet are different (at least by self-perception). And don't get me started on America's indigenous people being "indians".
TL;DR: Koreans may or may not be Han, depending on what you mean with that term. Who would have thought that ethnicities could be such a touchy topic? Definitely looking forward to your boss' take on this.
