That is definitely not a good starting point. WSL is much more complicated and prone to breakage than running a distro directly. It litteraly changes the whole system to make Windows run on top of a hypervisor. A better way to try out GNU/Linux is to boot up a live environment on a USB stick or use a VM. Plus, WSL is only command line, and I would think that showing a friendly desktop environment is the best way to blow the assumption of GNU/Linux being hard/only for nerds.
