When a program is minimized to the taskbar in Linux does it use less resources?

Usually not.

If the window requires a lot of resources to render (e.g. games, Video Player, etc) it may be that the minimized application detects that it's minimized and stops doing the resource intensive tasks.

But that's usually not the case. So the answer should be NO.

No. Its windows are not being displayed, but they still exist.

Yes, in some cases if the window drawing is expensive, e.g. a lot is changing.
