With enough calf strength, is it possible to lean forward (in ordinary gravity) so your center of mass is vertically above a point in front of your toes and not tip over? Like Michael Jackson, but without the shoe inserts?

nope. if the center of mass of an object is not over a support point, then gravity is necessarily torquing the object and it will rotate

And there's no way to prevent this rotation through strength?

I agree. Here's my favorite Robocop scene:

That's pretty good too. Robocop was an artistic masterpiece.

That's what a chimp do when he walks upright. His short lumbar spine means that he can't bring his center of mass above his pelvis so he can't do the balancing act that a human can do. The human can stand erect with small corrective movements to maintain balance while chimp has to use main muscular force to stay in that position and eventually tires and has to drop back to a quadrupedal stance.

Ignore my previous commemnt just above. I didn't read the question properly: the chimp doesn't lean out so far that his center of mass is beyond his toes but just beyond his pelvis.
