Is it even recursing in the tail position though? Reading the code it looks to me like the recursion result is used as an argument to a subsequent function call (append).

Spot on! The code fails as the author has used nil? rather than empty? The recursive call is not from the tail position so tail call optimisation is not possible in any language.

Afaik it is possible in racket. Read the note at the end here: http://matt.might.net/articles/lexers-in-racket/

You are right, should have said recursion instead.
