No; paper and cardboard chewing is a national sport for piggies!
Can you get some cheap fleeces from a supermarket, primark, or a market stall to put (prewashed) on top? I would recommend using something that is water resistant as well as wipeable underneath if you are doing it regularly, like a sheet of plastic or some cheap laminate. Alternatively, use cheap beach towels, they absorb more water than newspaper before they leak.
