Just NO!
Going by that, since CPUs with an exposed die have a perfectly flat die, then no compound is needed either.
Unless both surfaces are perfectly flat, thermal compound is still needed.
And even if you have lapped the CPU heatspreader and the heatsink to be pretty close to perfectly flat, thermal compound is still needed if you actually want good cooling.
If you don't use thermal compound you are going to at the very least get hot spots. At the worst you will fry the CPU in a very short amount of time.
