Not to mention two minds and nervous systems initiating and mediating all this (together with any other factors such as inertia and momentum I have not brought into discussion).
A major and constant component in the transmission of the forces generated is the feet with all the intricacies of their contact (or momentary/intermittent lack of contact) with the floor, modified by the levels of friction encountered.
So I ask myself whether the core, if it can be considered to have physical substance, can move itself without there being some initiating forces (however minimal) acting between feet and floor and consequently some trace movement at this level.
I have to conclude (though I may be open to persuasion) that 'the core' is indeed a concept rather than a physical entity, which probably serves a useful purpose in trying to explain the subtleties of a 'body lead'; but that, in fact, the lead is conveyed by the interaction of forces and movement at the points of physical connection with partner and floor.
