If you're OK with limiting your computer interactions to the 20th century, then yes, there's no reason not to run Linux directly. The most awesome thing about the WSL/Win10/Surface combo, though is that I get all the best features of Windows, including support for touch & pen, and all the best features of a real Linux box (which does make it way easier to keep your dev env like your deploy env.) I will never go back to a "caveman computer" that I can't write on to sketch and take notes in OneNote or similar apps. No Mac can offer that capability at any price.
