Yes, we just filed online for our N-400 (11/8/22) even though our I-751 Petition to Remove Conditions is still pending (we filed last year 11/10/21). I have read that N-400 cases are moving faster then the I-751's. In some cases they will do the I-751 & N-400 process/interview at the same time. (That is what we are hoping for🙂) By the way, The USCIS online N-400 filing was so easy to fill out... I recommend it highly.
