1 TB SSD for a MacBook Air Early 2014?
Is there any reason I should NOT replace the 100 GB SSD with a 1 TB SSD in my MacBook Air Early 2014?

The PNY SSD uses a standard M.2 SSD which won't work in a Mac without an adapter. Apple uses a proprietary PCIe SSD connector. OWC as suggested by @kaz-k is a safer option since the OWC Aura SSD is made specifically for the Mac and OWC is a well respected Mac friendly company with official support for their OWC SSDs installed in a Mac. If you end up having problems with other brands you may find that their support may not be that helpful when you mention Apple. In this case PNY could say the problem is with the Mac or the SSD adapter if you try to get support from PNY. Plus many SSD manufacturers do not provide a platform independent SSD firmware updater which are Mac compatible.
To use an NVMe based SSD in a Mac the computer already needs to be running at least macOS 10.13+ so that the system firmware has been updated to work with an NVMe SSD. You will also need to be running macOS 10.13+ on the SSD since the SSD requires the NVMe driver only provided by macOS 10.13+.
I would also suggest keeping the original Apple SSD just in case it may be needed later on to install a system firmware update or when upgrading to a new version of macOS. There has already been some cases at least with High Sierra and Mojave where the original SSD was required for an update or upgrade of macOS.
