Sure! You do whatever you want to do! So long you don't hold me responsible for shocks, burns, deaths, or worldwide power outages as a result. :P If what you are asking is if you can connect the negative of a DC power supply to neutral, most likely you can but it is NOT ADVISABLE.

Do some research on the power supply you are using to see if the output is fully isolated from AC. Also consider once you do that you now have a circuit that is connected directly to mains, if the circuit has exposed metal or wires, that would be effectively the same as sticking a fork into the larger reciprocal hole and leaving it there, and hoping that your household wiring is correct and the plug is the right way around.

Not touching this question with a ten foot pole. It's way too vague.

Yes, of course you can!

You can reference your ground potential (aka the negative wire) to any other potential you wish.

Well, of course then every part of you former DC circuit is now part of a mains voltage AC circuit. And if you live in a country where the AC mains plug can be inserted 180° around (e.g. anywhere in Europe) your former safe-to-touch circuit is now riding on the 240V mains voltage! Now you have a little death trap. Same f the wiring in a non-reverse-pluggable country is wrong.

So: Yes, technically, you can do it. BUT: Practically: NO, don't do it (unless you know what you are doing, have the necessary licenses to do so ....)

I didn't dare give it a qualified answer :-) The thought of the potential for disister horrifies me.
