Lin uses the uart, but to connect it to the Lin bus you need a transceiver.
Microchip do one, the MCP2021 which has a built in 5 volt regulator.
Or NXP TJA1020 is another popular transceiver.

You would be better off using the Microchip Lin Serial Analyzer.

It uses the PC USB port and it comes with software to drive it.
