no, it looks like it has nvme 2280 ssd in the model you mentioned and is already quite well equipped and fast. 2280 is cheaper than 2242 because it has a larger mass.
that would be the following products: https://www.digitec.ch/de...

Mass Storage

The system storage is an NVMe SSD from Samsung. This is an M.2 model (2280). However, the SSD is not in an M.2 slot, but is connected to a SATA port via an adapter. However, this is not a SATA III slot, but a SATA Express slot. The latter is the successor to SATA-III. SATA Express virtually combines SATA and PCI Express 3.0, i.e. not only NVMe SSDs can be operated at the connection, but also conventional 2.5-inch SATA hard disks. The data transfer is realised here via PCI Express. Up to four PCIe 3.0 lanes can be used. In the Thinkpad, 2 lanes (= PCIe 3.0 x2) are used. The maximum transfer rate is therefore 2 GB/s.
