It is possible to save all variables except one or two?

In a .mat file? Likely yes. If you have many variables in your workspace, the easiest way to include only those you want would be to use the who and then the setdiff function to exclude those you don’t want to save.

If you can write either

1. a wild card expression or
2. a regular expression

that returns everything excepting those you don't want, then yes. There isn't an -except option, however. It's been suggested but never made the adopted features list, never hurts to add your name to the proponents as a feature request at "official" TMW site www.mathworks.com.
