Nah, unless you want to call muslims christians as well. Once you start modifying your deity, like christians did to the jewish god, or muslims did about jesus being only a prophet, you’re a new religion. I’d say the same for when you change the basics of how you are saved (so I’d say that catholics and protestants are wildly different, seeing as catholics need confession and last rites to be forgiven or go to purgatory). Mormons hold that jesus and satan are brothers, that you need to go proselytize for a certain period of time, that there are planets instead of heaven (I guess heavenly bodies if we want to play with wording, whatever), etc.

Contrast that with the difference between methodists and baptists, or presbyterians and lutherans, where basically it’s all window dressing. You might get some proscriptions, like no dancing or drinking for baptists, but fundamentally the beliefs don’t change.
