As best as I can tell, the ThinkPad X201 has been out of production and even warranty support by Lenovo for a while. It is listed in Lenovo's End Of Life site, and the latest BIOS update I could find for it is dated 2013, five years ago.
Keep in mind that even if Lenovo is not providing a BIOS firmware update, your operating system vendor may be loading microcode updates into the CPU to mitigate Spectre and Meltdown, so you will be protected via that mechanism.
