No, as a leaf Carrara only can read one shade domain... I tried to group objects and didnt work. I posted this as a feature in the bug track more then a year ago and they never did nothing about that. What will really work is to use one shade domain and a texture, this way you can have the leaf in one color and the fruit in another.
Other way is to use my tutorial to create fruits that you can find in Daz, but its pretty simple: duplicate your tree and in one you add the leaves and in another you add the fruits...
