Absolutely. Most electrolytics are quoted with a tolerance of +/- 20%, and the circuits they are installed in aren’t tuned circuits, with the possible exception of power supply filters where the choice of the choke is related to the value of the capacitors, and even then, a 20% error is insignificant. And I’m pretty sure that the tolerance of early caps weren’t as close as 20%!

Regarding a rule for choice, I’d suggest that given two caps which might be a candidate for replacing a bad one, choose the higher value, and always choose a higher voltage too.
