It’s an interesting question. There are obviously cases where the answer is yes - if I were booked for surgery but the surgeon just sticks a knife in my guts and runs out, that’s pretty clearly assault and/or attempted murder. I’m not sure what tangle of laws parses out licensing and competence criteria to distinguish malpractice vs practicing medicine without a licence vs assault.
The wikipedia page for Practicing Without a Licence doesn’t provide any useful info, but does contain this passage that I found charming:
Victor Frankenstein, though often incorrectly referred to as a doctor, is only a medical student, and as such operated on his monster without a license. Prior to its vivification, Frankenstein and his assistant Igor were also acting as unlicensed morticians.
