Code in CCM RAM

I tried to put code in a CCM RAM (STM32F303) as described in AN4296 and I was very impressed. It was more than 30% faster, than if the code is in flash.

Mentioned PDF (AN4296) says that it is not recommended to place both code and data together in the CCM, because there would be a risk of "collision". Is that problem the same if I place in the CCM (beside code) a look-up table, which is a constant? Now I have it stored in a flash.
