No. The guide on AMD's website pertains to socket processors, it is current and it still stands. If you went to any of the AMD tech tour, you'd know that was an issue that was brought up. They still prefer PCTC.

AMD actually said that slot processors were fine with grease, but when you have a heatspreader that's nearly 6" long, why wouldn't grease be fine?

They do have two, non electrically conductive, greases on their list, but they state that they are not for long term use. For exmaple; if I was using one CPU to test several motherboards, I could use thermal grease as the machine would never be on long enough to go through enough power cycles to pump out the grease.
