To *balance*, yes. But to lunge, not at all. Ceneter of mass is of little
relevance to lunging. The key is that forward momentum carries the body
forward on a ballistic course. The main purpose of the rear legs in this
type of action is to sustain acceleration during the critical phase.
Just look at mountain goats butting heads - they are most certainly NOT
balanced over their center of mass during the suspended phase of the lunges.
