All objects in the universe (including the earth) are in a state of absolute
motion. Observed relative motion for two objects A and B is the vector
components difference of the vector component of A's absolute motion and the
vector component of B's absolute motion along the line joining A and B.

No ....you would not be able to do that. You can determine the state of
absolute motion of the earth surface experimentally by doing the experiment
described in the following link (page 3):
