Quisiera estar seguro que es generación 4... Buscando la referencia en Google aparece como generación pci 3!... Estoy confundido.

Estás en lo correcto. Es generación 3.

Will this work in a Thinkpad T480?

It works with any Windows 10 or 11 system.

Will this work in Lenovo Thinkpad Yoga 11e ?

Just installed this ssd after cloning. The ssd has full 512 GB after some manipulation as the cloning software created a C drive of only 128 GB, as the originally equipped. I needed to create a partition at the far end of the SSD and clone the partition. Then unallocated the partition behind the C drive but ahead of the aforementioned cloned partition. Using extension to combine the C and the unallocated partition gave me a C drive of around 450 GB as there were other partitions allocated for other things.
