First of all, why would you have one special copy of the kernel source? It's OK to have 42 copies or none at all. Giving a special status to one of them is a strange thing to do. Getting rid of /usr/src/linux helps you avoid the temptation to turn /usr/include/asm and /usr/include/linux into symlinks. If you fell to this temptation, you'd break your glibc install. Some would also argue that having /usr/src/linux encourages you to compile the kernel as root, and that this is bad. I'm not so sure about that, given that you'll be installing the code as root anyway, but you might care.
