Yup. You'll need to disassemble the keyboard and desolder the existing switch mechanisms from the underside of the PCB; then you pop them out of the mounting plate. Installation of the replacement switches is the reverse of removal.
Make sure you get a keycap puller tool, and if you're going to mess with any of the large keys (Spacebar, Shift, Enter, etc.) you may also want to get some spare stabilizer clips and springs in case you damage the existing ones.
The years just pass like trains. I wave, but they don't slow down.
