A: Unofficially, yes, but it is unsupported. You can take a generic Android-x86 ISO, install it in VirtualBox, then manually install the Google TV launcher via APK. The result is laggy and lacks Netflix/Prime Video HD due to DRM (Widevine L3).
However, there is a significant technical hurdle you need to understand first. Android TV does work like Windows or most Linux distributions. You cannot simply download a standard .ISO file, burn it to a USB drive, and boot into a live installer.
