I have an older 21" mower (21401P). My question is will the mulch plug that is for sale now fit any 21" mower?

Welcome to the forum.
There was no link showing the part that would be fit into your mower, but it should be fine.
There are two ways that convert a 21" Snapper Hi Vac into a recycling Ninja mower. One is using a plug in the chute, retained by the (unused) bag. The other is to remove / replace the chute w/ a recycling plate.
Both the plug and the plate are shown in this image. The side discharge is also shown.
