you can, but rather why would you want to do so.  Fat transfer is a filler treatment, in the same category as Restylane, Juvaderm,  Sculptra, etc., and Botox is a muscle relaxant in the same category as Dysport (and others outside the United States).  To my way of thinking, these two separate classes of injectables are best used to treat different problems.  If facial lines can be divided into those caused by muscular activity ("the hills"), and those caused by loss of  volume ("the valleys"), then each problem can be best treated in different ways.  The hills are best treated by relaxing the hyperactive muscles of facial expression to flatten them out, in areas such as the forehead, glabella (base of the nose between the eyebrows), Crow's feet or laugh lines by the eyes, platysmal bands in the neck, etc.  The valleys are best treated by filling them in with the fillers, treating deep nasolabial folds, marionette lines under the mouth, hollow area under the eyes, etc.  So, in general, Botox and fat transfer have their own differnet uses, and rarely need to be givn in the same site. 

muscle.  In the course of treating the neck in a facelift or necklift, fat is usually trimmed between the muscle and skin.  This can leave a "band" of the platysma muscle in the neck which is visible after the swelling from the surgery subsides.  I like to cut back the muscle in its mid portion in the neck to prevent the banding, and suture the remaining muscle on each side to itself to prevent this problem and give a smooth contour to the neck.  If there are visible bands like you are describing, Botox can be very helpful in softening the bands, although you will have to repeat the Botox injections as they wear off.
