They are already separate, if you look at the fuse panel one will be on the right side bus bar, and the other on the left side bus bar. If you are asking if you could add a separate service point and move one unit to it, sure. You would move the wires from the panel to a second "new" panel attached to the new service point. That service point would need to be a 30AMP service. Beware some CG do not provide separate 30 and 50 service at the post, just because the plugs are there do not assume separate runs.
