not really, at least not by any of the techniques I know of, at least not without knowing the height of the objects on the horizon. In theory a mountain on the horizon could be a thousand feet high and far away, or ten feet high and quite close. What we can determine is that the mountains are in fact 3D as they change with parallax as the camera moves.
It may be possible to determine their distance if you can locate a stereo-pair of images, but I think that you'd still need to know how far apart the images were taken to get results.
Having said that, it would likely be able to determine things like how far away the rover or LM is in some photos since we know their height, and it could be possible to determine how tall a mountain is based on that information and the change in hieght of the moutain with the change in distance over several photos, though I wouldn't be totally sure of the math.
Actually it is possible to reconstruct a 3D model using two or more photos taken from different vantage points. So long as they show some common features and there's at least one known dimension. Software like Realviz Imagemodeller will do it. The problem with modelling all the way to the horizon though is that parallax will reduce to almost nothing and so accuracy will be a big problem. I think you'll most likely find it working in favour of the hoaxists, since they could do an analysis, ignore any pesky accuracy issues and find a horizon that is only say ten miles away instead of 20 (made up figures here). They'd have no problem thus declaring the photos fakes, but completely disown any notion that their soundstage would still have to be ten miles wide.
