If you are an implementer, you certainly can provide such a procedure.

If you are a user, and you care about standards conformance,
you should choose a different identifier, as 1+x has never been a
standards-conformant identifier under *any* version of the Scheme
standard.  However, most Scheme implementations will accept 1+x as a
valid identifier.
