Here is a recipe for an action in Photoshop, which works for this exact image (or other images using the same colors and principle). I suspect that the images you want to process have might have other or additional colors or some unknown complexity which could make this method worthless (or at least in need of tweaking).
You mention in comments that your ...

This is for GIMP, and the same would be possible in Photoshop.
Although not perfect, using your second image as an example, it would be possible to select the green area using the Fuzzy Select tool (aka Magic Wand), and remove most of it using a curves adjustment on the green channel by pulling a curve, then maybe increase the brightness and contrast. ...

I did this in Photoshop, but Gimp has similar tools.
I just thought the quickest way was to brute-force it ;)

In this example I make a selection, move the selection, choose the Move Tool, and get the "the selected area is empty" warning. ...

Lock transparent Pixels means.... don't allow transparency alteration to any pixel which has transparency.
Why you appear to think you should be able to then alter the transparency is a mystery to me. The lock transparency command could not be any more clear in my opinion. This command is helpful when you have partially transparent pixels and need to alter ...

Your selected area is, in fact, empty.
It doesn't contain transparent pixels it just contains nothing.
You can select it because you are not selecting 'pixels' as such but simply 'an area'.
Filling the area with the paint bucket etc it then defines that area to become coloured & then will contain pixels.
Trying to move the selection with the Move tool is ...
