Yes you can, we used to have rabbits and we were able to bath them. However, they dont really like the water so you have to keep a firm hold on them! Just use a gentle shampoo formulated for animals. If you cant get a shampoo specifically for rabbits (I have seen one in Sainsburys) then a gentle puppy shampoo would also be suitable. Just be careful not to get any in your rabbits eyes. Hope this helps.
