No, not hum. It won't cause anything bad to happen from an obvious standpoint but it will cause subtle degradation. I'll explain. Every piece of gear creates hash and noise from it's power supply and this noise is put back onto the power line. The noise is generated mostly by the diodes which are converting AC to DC.
When two units are plugged into the same outlet, the self generated noise can contaminate the power and you get slightly poorer performance out of the equipment. So, we add filters which are one way gates so that each outlet is isolated. Only, the isolation is not perfect. It does help, but it doesn;t fix completely.
So, this is also the same reason people have dedicated lines coming into their rooms. You can certainly do what you asked about and no hum or obvious bad things wll happen - the advice I gave was based on getting the best performance out of what you have.
