PS4: Possible to install full game and demo version side-by-side?

I have a friend who is interested in FFXIV and does not own a PS4 (yet). His PC is very old and cannot run FFXIV, so I want to let him play the demo in my PS4.

Is it possible to install the full game (the one I usually play on) and the demo version on the same PS4 console, or would that damage the installation of the full game?

All the best,
Zazanima

There is no demo version, they are the same client. Only thing different is the trial version doesn't give you a key.
