Baking powder, while it contains sodium bicarbonate, also includes an acidifying agent (cream of tartar) and a drying agent (usually starch). So, yes, you can substitute baking powder for bicarbonate of soda/sodium bicarbonate/baking soda, but you'll need more baking powder, which may affect the taste.

What does bicarbonate of soda do?
Bicarbonate of soda, or baking soda, is an alkali which is used to raise soda breads and full-flavoured cakes such as gingerbread, fruit cake, chocolate cake and carrot cake. It needs an acid (as well as moisture) to activate it so is often combined with cream of tartar, yoghurt, buttermilk or milk.
Is sodium bicarbonate the same as bicarbonate of soda?
Sodium bicarbonate and bicarbonate of soda are one in the same -- you may know it better as baking soda. This chemical compound has uses that go beyond acting as a leavening agent in your baked goods. It's a safe ingredient in food, but if you're using it as medicine, talk to your doctor.
