Naaaani?!??! Chigau-yo!
The cells of the heart muscle differ from other muscle cells only in that their contractions are automatic (as you can see by looking at one under a microscope). They only require external stimuli to coordinate their contractions, or you've got fibrillation and the blood doesn't get pumped. These muscle cells don't "expand" any more than do other muscle cells.
Back to topic: sure, one can punch without force added via the calf muscles which lift the heel. While one is at it, one can also consider other handicaps: tie a hand behind the back, wear a blindfold, and so on.
Why, though?

Anyways, that's true within the punching mechanic you describe.
Another way to look at it, is to look at a person's two legs as having a similar structure as that of a bridge. If you can connect both legs as an entire unit, you can pass force through the "arch", or in this case, both legs.
This means that the power generation, can come from front leg, pass through the "arch", and to the rear heel, and at the same time travel upwards through the crotch, out the spine etc etc
Verbally, all this is kind of useless to explain, but there is a significant difference in feel.
Summary, you can get an extremely heavy punch that naturally uses 100% body weight, without committing your body weight in any one direction (sounds contradictory, I know), and expending much much less energy.
No forceful using of the calf muscles to drive the heel up is used either.
The downside to this, is that it's a skill that takes a while to learn and also requires conditioning of the body that's pretty unusual to most people.
Then you can get into other additives, like using the stretch of the fascia to add to the power of the hit etc, slamming the diaphragm down, causing the force to ricochet into the legs and back up, in order to produce power for the hit, etc.
Again, this stuff needs to be felt, and can't be simply explained in words.
