This indicates rfkill is effectively blocking the wlan: "radio disabled"

There is a directory /var/lib/systemd/rfkill/ which holds a file named
by the Wi-Fi device. Here it is pci-0000:04:00.0:wlan. The content is
just a 0 for normal operation or 1 for Wi-Fi off which means RF_Kill.

Please check that file on your system and replace a possible 1 by a 0.

There is no /var/lib/systemd directory on the laptop:

Maybe it's elsewhere in /var ?
$ find /var -type d -name rfkill

Or in sysfs :
$ find /sys -type d -name rfkill

Else, look everywhere ^^

Things to check :

Check the status via systemctl (didn't know there was a service):
# systemctl --status rfkill

Is the rfkill *module* loaded ?
# lsmod | grep rfkill
If nothing, try loading the module :
# modprobe rfkill

Is the rfkill *tool* installed ?
# dpkg -l "*rfkill*"
If not, install it
# apt install rfkill
