I don't know, but my guess is that anything goes. As long as users are clicking both ad sets then TLA and Google are both happy.
I am an affiliate for online companies. I place ads (my affiliate links) to different companies on the same page and do well. Why would Google have different rules for placing ads? If Google Adsense does have a rule that says no TLA on the same page, I think that is rediculous.
If your question is: is placing TLA and Adsense on the same page bad for Search Engine Optimization? My educated guess is absolutely not - anything goes.
