I am experiencing the issue on X1 Carbon laptop, but it seems that the issue affects all Thinkpads. Here's a link to a similar report for a different model https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310248
It appears that the code in charge of handling the X1 Carbon adaptive keyboard is here and rfkill handling is there: https://kernel.googlesource.com/pub/scm/linux/kernel/git/jic23/iio/+/refs/heads/togreg/drivers/platform/x86/thinkpad_acpi.c
Pressing the key generates no events (see below) and thus has no effect.
So, it's either my stock kernel doesn't have it, or something else is broken.

So, since nothing fires on both channels, it seems I can't manually bind the button to rfkill either.
As temporary workaround I had added a custom rule to /etc/acpi/events and bound handling do a different adaptive button that does generate a acpi event.

On my X1 Carbon laptop the wireless switch key doesn't work. It appears that the code in charge of handling the X1 Carbon adaptive keyboard is here and rfkill handling is there: https://kernel.googlesource.com/pub/scm/linux/kernel/git/jic23/iio/+/refs/heads/togreg/drivers/platform/x86/thinkpad_acpi.c
