Well, the answer is yes, but not as you expect: If you have a virtual 
machine running only accessing a local filesystem, you can create a 
snapshot.

So, for other practical purposes and in the sense but not wording of you 
question:
No, environment variables are part of the OS (or the shell).
If you want to save EVERYTHING this way, you'd need an image of both, 
the RAM of you machine as well as the current state of all filesystems etc.

Best,
