Using pre-existing textures skins of an machine that i “emulate”?

I have desided that different parts of my game will take place inside 5 different graphing calculators. This wont be exact emulation of the calculators, but rather a simulation. So the question is – can i use preexisting skins in my game and submit as compo?

By “skins” I mean this: https://github.com/rogersachan/Wabbit/blob/a41282980e58aecc7ba038abbed4c0fa93b483d2/WabbitStudio/Source/Wabbitemu/gui/TI-83.png
