Are you supplying editorial? If so, the brand name would be needed.
If not editorial, it's unlikely to be accepted if it's a recognisable brand (unless you have a property release from the manufacturer or maybe if it's a small part of your picture).
What she said, same thing simpler words. If you use any trademarked or copyrighted name in the description or keywords, you should get rejected. Sorry that's the life in the world of micro. You can't use someone else's name in your descriptions because that's admitting it's their proprietary product in your photo, and then you would need a release to use their product in your image.
