No, the games you're referring to are written to use the entire screen. If you want to make an existing app do that, you'd have to decompile it, rewrite it, then recompile it. It's possible but, unless you've had at least a few years of experience developing android apps, I doubt that you could do it. (It doesn't actually require mind reading, but at times it seems as if that's what you're trying to do. "What the heck was he trying to do here?" when the code you're looking at doesn't seem to make sense - it did to the developer, so if only you could read his mind.)
For all practical purposes, no, it can't be done.
(I suppose someone could write an app to cause apps to write to a "larger" screen - but I have no idea what effect that would have on the phone. And that's changing things at the system level, so it might require rooting. I don't know - I've never tried mangling Android like that. CP/M, yes. DOS, yes. Even Windows and Netware. But not Android.)
