Even though I’m 40 and my dad never leaves couch I strongly believe that he can win easily in any strength competition (involving arm strength to be precise).
Is there something biologically different in muscles as we get older that makes muscles stronger, and we don’t have to exercise as much to keep them that way?

Generally no. Cracking walnuts with your hands certainly requires some strength, but not exceedingly much. A certain disregard for pain also helps. And you need to put two walnuts in your hand – one of them will focus the pressure on one point and break the other. If you practice long enough, you can do that trick.
