Yes, they are compatible. Follow the disassembly and reassembly steps in Dell's Service Manual. Before removing the wifi card, go into Device Manager and uninstall that device and select the checkbox to delete the driver software. Note that if you currently have an Intel Optane drive, you must disable it before removing it from your computer.  Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard.
