It is exactly the same. I put Windows 10 on an older Dell laptop. It mostly works, but it's not "supported" and I get blue-screens once in a while. There's just no practical way to keep supporting arbitrarily old devices, even for a company like Microsoft.
If it's exactly the same, I will hand you an unbranded phone with no OS and see if you can get Android running on it. The only machines you can't get Windows running on right now are Chromebooks, so 99% of personal computers will let you pretty easily install Windows in exactly the same fashion you would on any other computer. It might not run well, but it will certainly install. If it's exactly the same, do that with Android on any random phone.
