es this imply that the rod is malleable/contractible
It implies that the rod is not perfectly rigid; applied forces do not act everywhere in the rod instantaneously. Whether the result of that will be the rod contracting, expanding, or something else depends on the particular forces applied and where on the rod they are applied.

does that then reflect the contraction of mass as in the Lorentz contraction?
No.

Or is that a separate and unrelated concept?
Yes.
