The regular uni-knot used in attaching tippet to hook or for using double uni-knots to attach tippet to leader, are different from the nail knot in application.

But there is a different use and application for a uni-knot that is described in Art Lee's book "Fishing Dry Flies for Trout in Rivers and Streams" that is called the Uni-knot splice, and is used in the same application as the nail knot (fly line to leader).

It seems as if the uni-knot splice has the same result as a nail-less nail knot.

The knots are tied in a different way, but apparently have the same end result.

Here is a picture of how to do the uni-knot splice, as is indicated by Art Lee:
