No, UK regulations aren't stricter than the US. They are just different. The UK tends to focus on CO emissions, while the US tends to focus on NOx emissions due to the link between NOx and smog. An engine optimized for CO may not be as good on NOx, and vice versa. The US vehicles are using urea injection as post-treatment to control NOx. That will eventually come to the rest of the world, but in general, engine control strategies differ enough that we will see engines certified for one region or the other, but not necessarily both, for some time.
While that may not prove you wrong, it does take away the apparent motivation not to sell the 40d in the US based on kickbacks to executives.
Don't sweat the lack of certification for the 40d. It is older (last generation) technology anyway. The next model will be the triple-turbo 45d 3.0 litre, that will be worth waiting for.
