You agree not to display on the same Web page in connection with which any Ad Unit, Ad, Link, Search Box, or Referral Button is displayed (a "Serviced Page") any advertisement(s) or content that an end user of Your Property(ies) would reasonably confuse with a Google advertisement or otherwise associate with Google.
That's a direct quote from the TOS. If you are running the same creative, that sounds to me like it could be mistaken for a Google ad. The tiny arrow - I would bet that's not enough.
But the bottom line is, is it worth risking your AdSense account for? If you think it is, then go for it. If it isn't, then don't.
