There is no exact definition but it comes from one of the Distiller settings in the Acrobat product range. I.e. one of the settings for the program which converts PostScript files to, in this case "press-optimised", PDF files. I don't know what those settings are by heart but basically it are settings which prevent Distiller operations which are nefast for prepress purposes (like reducing the image resolution to e.g. monitor resolution). Like you've already indicated my guess is that the RGB data might cause issues but on the other hand there is definately a trend to have an RGB based PDF workflow as well (usually as PDF/X-3 file format). Basically this would mean tagging of the RGB data in the PDF document which I think isn't the case for the ArtWorks PDF files. Basically I would simply ask the company you're supplying your PDF file if they have a problem with RGB PDF files.
