If you are using Adobe Flash to consume your models (via ActionScript calls to any of the APIs) then probably, but you won't find anything on the IBM website to tell you as much and you'll need to talk to your systems administrator/ IBM Partner.
If you don't then you 'may' be checking compatibility with the Cognos Lifecycle manager in an older version of Cognos BI which again entails a chat with your systems administrator/ IBM Partner.
