you really want something like tomorite which is a high potash feed ( if you look on the bottles you will see that the amount of potash is more than the phosphorus or nitrogen) potash encourages flowers and fruit, when the values are the same its called a 'balanced fertiliser'

Baby bio will not give you the results a liquid tomato feed will.

Baby Bio is intended for foliage houseplants, so has high nitrogen levels and low potash, so the answer is you can, but I wouldn't advise it - you'll end up with lots of leaves and not too much fruit.
