Can u use a 3s battery on a plane that requires 3s with out anything happening?

Like my plane needs 4s and I have only 3s's can I use it without it breaking or something like that.. I don't mind if I get less flying time I just want it to work
I have several planes set up for four or six cells though I normally use three cells. With these planes, a swap the prop to a larger diameter APC slow fly prop and, if I have too, use two batteries for balance purposes.
