No. The N900's kernel is the full, 'desktop-grade' Linux. Everything else you see and have on the device, is 'addons' to make it more useable. http://en.wikipedia.org/wiki/Linux - Linux IS the kernel, the addons make it a distro/flavor. Even though the kernel can also have different 'addons' in it, it doesn't change the principle behind it. Might I ask what you consider 'Linux'?
