Not a wise idea. One post I do disagree with. Dealers voiding warrantee if they find red fuel is questionable. Red fuel is exactly the same as regular #2 diesel with the exception there is red dye in it. It has NO effect mechanically on a engine. If you had a separate fuel tank for your diesel generator you could legally use red fuel in it.

I would guess the warranty may specify it is for normal use and offroad only use is prohibited or excluded. So if you are tested positive for offroad fuel it is a tacit admission of the activity. I do not know this for fact as I have never had the desire to actually read the fine print in my warranty.
