Maybe if you have them running off separate controllers. The signalling per board is common-ground 3.3V digital, so if you hook up the boards like that the controller will be tying ground to 12V and something will either trip out or catch on fire. With two separate controller boards (one for each hash board), each will be operating at local ground.
If you had two entire S5s, you could string the entire machines, which would give the controller the same ground reference for both boards (one controller and two boards at 0V, the other set at 12V).
Since ethernet uses isolated signalling the difference in ground potentials shouldn't affect the networking.
