Pizza boxes can be recycled as long as they are not heavily contaminated with grease or food. The reason that cardboard contaminated with food and grease is a problem is because the food cannot easily be removed, so it means that when the cardboard goes for recycling it contains cardboard and food - manufacturers don’t want their cardboard to be mixed up with bits of old food. A lot of grease is a problem because it makes the fibres in the cardboard stick together so that it is more difficult for the cardboard manufacturers to separate the individual fibres for making into new cardboard.
