Your network can be compromised if the device is connected to the same network as other devices. However, most modern routers support a guest WiFi, which may be a good fit here.
In the previous company I worked for we provided alternative laptops when traveled to China, as it is enough to connect to a hot spot to get infected.
With that said, if your father in law has other devices, worth connecting them to the guest network as well.
