Yup! Lenovo could have done it, but didn't implement it. Admittedly, there's not a standardized way to do it either: Macs actually save Wi-Fi AP details into

Yup! Lenovo could have done it, but didn't implement it. Admittedly, there's not a standardized way to do it either: Macs actually save Wi-Fi AP details into SMC or NVRAM (can't recall which) which is why wireless connectivity is accessible without setup when in the BIOS and recovery modes, but there's no analogous part in standard IBM-compatible PCs. Speculating, but this avenue could hypothetically be a security issue too if it's not secured well: attackers could extract confidential AP details without having to bypass full-disk encryption, or attack live RAM.
