Since the compressor produces compressed air, it would certainly work, given you build adequate fittings and take precautions against overpressurization. LEGO pneumatics have been tested to withstand as much as 8 bars or 120 psi, but you definitely should plan with safety margins. If your compressor can produce higher pressures, I'd suggest building in some ...

You will not destroy the air tank using standard LEGO components. I don't know what it's structural limits are, but I can tell you that the weakest link in the pneumatic system in my experience is the connection between the rubber pneumatic tubes and plastic inlets. Under high pressure, the tubes will simply pop off before any of the components will actually ...

The pneumatic system's limit is three bar (40psi). After that point, the hoses will pop off the ports. I don't think you could explode the airtank very easily with a real compressor. My guess is that it would start deforming around the 5-10 bar range, and only explode once it was bordering on spherical :P.

An air tank (at least LEGO low capacity ones) are not meant to directly supply actuators. Their main purpose is to smooth out the pressure of air flow produced by a pump (manual or motorized).

I was going to recommend lubricating the pistons, but seeing you already did exactly that, I can only say you should try to isolate the source(s) of the problem. Since you have at least one working cylinder, the compressor and the feed tubes should be all right. This leaves the following possible points of failure: switches, subsystem hoses, working ...
