Not sure what you mean ... compressibility factor is a way of combining measured data to determine deviations of real gases from ideal behavior. The vdW equation is a way of understanding/explaining from first principles how non-ideal behavior arises from microscopic interactions between gas molecules.

If you have sufficient data on the compressibility factor (which is not a constant but varies significantly with pressure and temperature), then you could fit that data to the vdW equation and extract specific values for the vdW constants.
