No. In my experience, the vast majority of collectors would reject them if the precise cause of the "gum disturbance" was misidentified in that way. I believe you are going to have to describe and show the issue with a scan of the back, or you risk having problems with the buyers.
If they are not valuable enough to put in that effort, do them up as a lot and show samples of the backs.

I've never had that happen with the mounts I use. It seems like they must have been exposed to dampness at some point. If we are allowed to use the term hinge remnants why not show a couple and call it mount remnants if you decide to sell?

I have about 100-150 mint Russian stamps which I acquired in an album in mounts. When I removed the stamps from the mounts, some of the mount adhered to the back of the stamps. If I sell these stamps, do I describe them like I would if they were hinged? 
Here is a scan of one stamp that I have.
