You can certainly land in Paris as it is listed as an unofficial airport. Keep in mind though that the cost in time goes up.
From the rules:
* Additional Listed Unofficial Airports from the 1930s. These are contemporary airports with good facilities. However, the RAeC will not have prepared the local officials and airport staff nor will they have RAeC officials on hand to expedite matters. It will take additional time for the landing pilot to find and engage the airport maintenance personnel, to negotiate with the local government officials, and to arrange the appropriate payments. Refueling stops will take longer than at the RAeC official control or checking points: 90 minutes rather than 45 minutes.
