Yes but you'll still need a satellite feed into the second room where you want Freeview. You'll also need to get a Freesat card from Sky for a one-off fee of £150. You will get a lot more channels than Freeview, but they will be the free to air channels. You can use your Panasonic box without a card, but you won't be able to get Channel 4 or 5 on it. It might also be cheaper than £150 because you already have the box and are a Sky customer, but discuss the cost with Sky.
