There are absolutely NO possible hazards to this, from perspective of Win10 VM. Since it is a virtual machine, you can move it wherever you want, you can even change the complete hardware on which it runs, it will make no difference. Virtual machines are made to be flexible and most of all easily movable. That Win10 VM will have NO IDEA that you have changed the underlying filesystem or disk.
