Yes. Or at least it was in 1981. tl;dr I was accepted into two Ivy League CS Ph.D. graduate programs with them knowing I wouldn't have a bachelor's when I got there and wouldn't get one.
Longer version. At a "public Ivy" university, I had finished all the requirements for a CS B.S. in three years...except I needed one full semester's course load in, well, anything. Number of hours was all that was between me and a Bachelor's. I checked with a fair number of schools that had "Must have Bachelor's degree or reasonable equivalent" in their catalog, explained my situation, and said I had three professors who knew my situation and would write recommendations for me. Most said "No, but you sound interesting. Try us next year if you don't pull this off". Two Ivies and a Canadian university said I could apply. The Ivies both accepted me and I withdrew my application from the Canadian one before they decided.
Didn't manage to pull off the Ph.D. though; my inexperience at 19 had me not realize it's important to find out about personalities and reputations among faculty for grad school, and it turned out my advisor/dept. chair liked to flush a majority of his students (I was the fifth of my entrance year). It turned out to be relatively simpler to get my graduate hours transferred down to my undergrad school and pick up the Bachelor's that way and then get admitted elsewhere.
Things have changed significantly for graduate CS admissions at good schools in the last 40 years though. Generally you're now expected to have already done some research, and you should have a really positive recommendation from whatever faculty you did that research with/under. I suspect your best approach would be to first get a "professional Master's", but since those usually don't involve research, also get on a research project while there and impress the professor(s) running it.
