Re: Thought Experiment
@AC all good points, but there is one more thing. License of Linux kernel does not apply to "combined work", since this term has only been added in GPL version 3, and Linux kernel is only distributed under GPL version 2 (without the option to upgrade license to GPLv3). In this version of GPL, the relevant terms apply to "derived work" which, arguably, is a different thing from "combined work". In particular, an external module not making use of any functionality which is very specific to Linux, can be argued to not constitute a "derived work". It is still an open question whether the whole distribution, or its part, can be called "derived work", and if so, what implication does it have for Ubuntu 16.04.
