Traditionally, Canon have reserved the "supertelephoto" category for the primes with FL of 400mm and up. That way the 400 f/5.6 qualifies, while the 300 f/2.8 and 200 f/1.8 don't.
A looser interpretation would be according to provision of fluorite elements. Obviously, that would exclude the 200 f/1.8 as well as the 400 f/5.6.
Lastly, one often finds a popular usage of "supertelephoto" is reserved for the 300 f/2.8 and any other lens priced higher than that.
Then you'd include the 70-200 4L since it's also got a fluorite element...
When I talk of superteles, I generally include any lens with an aperture over 100mm or with a 400+mm focal length. I.e. 200 1.8 (111mm aperture), 300 2.8, 400 5.6, etc.
Granted, I also consider lenses under 70mm a wideangle....
