The 14 pin Bluetooth Daughter Cards (BDC) are USB Bluetooth Adapters that are installed in a proprietary BDC socket. The connection probably carries usb, power, led and enable signal. The antenna is printed on the PCB. The location varies by model (within the screen, under the palm rest area, etc.); refer to the Hardware Maintenance Manual for the location of the BDC.
Very likely, all BDCs can be interchanged, allowing newer Bluetooth adapters to be installed in older ThinkPads. The Bluetooth 4.0 module has specifically been seen advertised like that by dealers and photos of different modules reveal no mechanical incompatibility. – Nevertheless do some Hardware Maintenance Manuals require using an M2 screw for one BDC and an M2.5 screw for another.

When Bluetooth is enabled, the Bluetooth-logo LED will light up and executing
# lsusb will show an entry mentioning "Broadcom".
On recent ThinkPads the Wireless killswitch disables both WiFi and Bluetooth (verified on a ThinkPad Z60m, Z61t, T60, T61 and X61).
ThinkPads without BDC socket
Not every Bluetooth comes via 14 pin Bluetooth Daughter Card. The X130e, X140e and the X240 for example use combined WiFi/Bluetooth mini-PCIe cards instead. Older devices use the Communication Daughter Card slot to provide Bluetooth.
