Yes.

Although I think animal bone as is, is at its theoretical maximum for strength. You'd need to go back to the drawing board for a support structure stronger.

If you look at the large mammals we have, per gram their bone is about the same strength as ours. Selection will select in stronger bones at a lower mass in every species pretty evenly, because it takes fewer calories to drag it around.

You could see bigger animals in a lower G environment, obvs.
