Yes sometime people wrap their thumbs over the top of the neck to be able to get that 5th finger on the fret However these are more, non-traditional chords, and I've personally seen them used a lot in rock and metal.

That sounds has been called "fret noise" as long as I can remember.... Maybe the term "technically" isn't correct, but it's the going term for describing the sliding noise achieved from the friction of one's fingers going over the wound and unwound steel strings.

A more "realistic" noise caused by frets would be "buzzing". Meaning the guitars neck may not be completely straight, a fret could be pulling up and so on. Actually the Ovation I used in this demo suffers from "fret buzzing". That's of course my fault. The last time I put strings on it I removed (2) risers from underneath the saddle to lower the action. It really didn't need it though The stock action is already close to an electric I guess I had too much time on my hands. Now I have to put at least (one) riser back to get rid of the fret buzz.
