When I used Adwords back in the day, end of last year, they pulled the 'does not meet LP guidelines' card in certain niches and in others they didn't. In my experience they blacklist certain verticals that are prone complaints, like colon cleanse etc.
If I was you I would get on the phone and call adwords, speak to someone and ask them what they think. They will most likely tell you to read their guidelines, so take their name and call them back the next day and ask for them by name. Keep at them until you find out what you need to know.
