I cannot imagine any reason why not. Most everything done in Unity can be done with Godot, just perhaps with a bit more work. Unity has several functions that make things easier, but with a little work you can write the same functions in Godot.
Some tutorials could require editing the source code (like getting a UV position from a collider) but for most cases I highly doubt you'd ever need to use anything but GDScript/C# if you wanted to.
