I am still using old RCX and serial IR tower for my projects.

I have a question about old IR tower, can I use a 9v power supply to this tower instead if 9v battery?

well, it should work of course, but make sure that you have DC and no AC!

Is it possible to damage IR as overhead current?

if you make sure the polarity is right and the voltage is correct (DC and indeed 9V), it should just work. Don't worry about current, the power supply should be at least be able to draw enough current, but that is not a problem with just the IR tower I think (otherwise you would overheat the adapter). Be ware that the LEGO adapters are mostly AC.
