Boxing
"Amateur" boxers
cannot fight above (or below) their weight class, as stated by the Amateur International Boxing Association (the seemingly most well-regarded amateur ruling body). The lower bound of a weight class is also
a requirement to fight at that weight. Oddly enough, this is also the case for the Summer Olympics.

Pro boxing is a little trickier, as there are 4 different major boxing organizations - the IBF, WBO, WBA, and WBC.
Fortunately, they seem to have more or less the same ideas about minimum weight, namely that there isn't one. A fighter is free to fight above their weightclass as far as I can tell, at least from the WBO and IBF rules.
One thing to note, however, is that to challenge the holder of the heavyweight championship belt, you're going to have to be ranked pretty high within that weight division to even
get the chance. That means winning several fights with a pretty
drastic disadvantage. In reality, I doubt they'd ever let a fight between fighters of that large a weight discrepancy ever happen. And personally, I'd probably take my extra 80 pounds of
pure functional muscle over quickness any day.
There are also
"catch weight" fights that have limits outside the usual weight classes. The limit is typically agreed upon by the boxers themselves beforehand.
MMA
The MMA has
similar rules to amateur boxing (at least in the United States), as athletic commissions from several states came together to write the
Unified Rules of Mixed Martial Arts, which states fighters must fight within their weight classes.
