When picking a caliber for my new AR build, can I swap between 223 and 7.62x39 by just changing out the upper and a magazine or do a lot of other parts need to change as well?

I think so, As long as your including the bolt as well when you mean "upper".

That's correct, all you need to do is swap the complete upper and use the appropriate magazine.
