Yes, you can but getting the correct adapter may take some doing as BroadCom has discontinued the part a while ago as a different interface became more popular.
Here is the IFIXIT guide: [guide|10757|MacBook Pro 15" Unibody Mid 2012 AirPort/Bluetooth Board Replacement]. And here is the part from one source: [http://www.quickertek.com/products/Ucard.html|uCard].
The other option is to use an external USB adapter or use a AirPort Extreme unit which you connect your Macbook via an Ethernet cable.
