You could add it through a teachpack implemented as

  #lang scheme/base
  (require lang/htdp-advanced)
  (provide (rename-out [lambda λ]))


I'm not sure why `λ' isn't already bound in the HtDP languages. I'm
sure that some of us have discussed it, but I don't remember the
conclusion (i.e., whether we decided that it was a bad idea or that we
just didn't get around to adding it).
