Not unless you have some licensed software locked to a particular ID, no.
The only possible problem is if you guess a number that matches another
Sun on your network and you'll have all sorts of fun.

I've done it for every sun4c machine I've ever had. At one point, I
had a regular expression to grep out six letter words from /usr/dict/words
with a-f and perhaps i and o. There are a couple more than c0ffee, but
that's the canonical one from the NVRAM FAQ.
