Fans frequently post conversion notes (monster stat blocks, trap conversions, alternative treasure, etc.) without mentioning Golarion. Seems like it would be possible if you knew what you were doing.
The DMGuild has a very specific user agreement that relates directly to the use and reproduction of IP. I am not sure what use a conversation document could be that did not directly reference an AP and the Paizo trademarks found therein, but even if one could manage to put one together it would be a simple matter for Paizo to claim (rightfully) that the seller was trying to profit on Paizo's IP and get it shut down.
