Actually, they are OK because they are not Amazon.com affiliates but rather Amazon.co.uk affiliates - seems Amazon treats its international sites more liberally.
Heres another relevant section from the Amazon.com (US) associate site:
"Associates may donate their earnings to a charity, but may not announce to their visitors in any way that a portion or all of the proceeds will go to a particular charity."
