You “can”, but to reduce the possibility of ground loops and interference between electronics, you should connect all negative returns to the ground bus bar.  If you cannot upgrade the bus bar you would be better off “double lugging” the second battery to your ground bus bar than connecting it to the negative terminal of the first battery.  See the diagram below and in the following link.  Add-A-Battery Kit - 120A
