Indeed. Linus said nowadays kernel modules developed with Linux specifically in mind are less likely to be considered "not a derived work" as early days kernel modules.
However, how about user space programs designed specifically for Linux, and even using Linux specific system calls?
It's definitely a grey area here, and it's not so clear that kernel-user boundary is stronger than kernel-kernel boundary per se. :-)
Note kernel-user boundary is not just normal system calls. /proc, ioctl (provided by kernel modules) are also part of it (which are system calls too but they can be arbitrarily extended).
