Well, it kind of implies that you might be breaking the license agreement which could lead to the revocation of your license.
That said, we can see that's not the case here.
Though bear in mind if you are using the files from a different license and they have different product/add-on entitlements and different expiry dates then that could lead to some tricky situations.
So, no, not harmful right now, but it could be. We'd highly recommend using the correct files for the correct license.
