Combined weight limit on check in luggage

Hi! We're tourists travelling from Zurich to Munich to Paris. Question is, if I buy additional baggage for 2 (economy light doesn't include checked in luggage) and we only have one big luggage over 23kg but less than 30kg will that be allowed? If I buy for 2 people worth 23kg each, then combined limit will be 46kg. Do they allow that combine weight limit? Hope my question makes sense. Thanks
