From a basic tech perspective, yes. Offloading working data from the primary drive frees up capacity elsewhere in the system. From a more practical standpoint, it depends on the speed of the new drive, how the pcie lanes are divided on the chip set (a wifi slot might share bandwidth with the primary disk) and a whole host of other minor items (power draw, thermals, etc) that might aggregate into you not noticing any difference at all. That said, it’s generally a good idea to keep working files not only backed up, but on different physical media so that having to format your OS drive because of some wacky error doesn’t cost you what you’ve been working on. It’s far easier to swap a nvme drive to a different laptop than it is to try recovering the data if your disk controller fails
