In theory yes, in practice USCIS denies cases for no show every now and then, even when reschedule request was submitted and acknowledged. I'd follow the golden path (no reschedules, all evidence submitted) to lower the chance of erroneous denial. Also, why make USCIS work on case if not ready to naturalize? This slows down other people who eagerly wait for their case to be decided, ready to go to interview / oath any moment they're invited? It's like joining long airport security line only to ask somebody to hold your spot when it's your turn to go... Can do if really want, but it's somewhat a waste of everybody's time.
