I have no idea of why not. The war was indeed mainly trenches, but it was not all of it. There were many moments and battles that took place elsewhere and that could be used to make a truly engaging game.
And then we also have "fiction", in case anyone forgot about such a concept in a video game.
Anybody remember the historical and accurate depiction of the WW2 and its Nazis in the Wolfenstein series? Well, imagine a WW1 with some Call of Cthulhu elements added to the mix, or steampunkished personnel and/or their machines.
Or simply some real events but modified or intertwined with others to accommodate the discerning user's need for adrenaline.
I am sure that it would not be a real problem just out of lack of imagination, specially for any developer with the desire.
