I think the shortest and easiest answer to this question, in practice, is "no."

While it is possible to write programs that conform to a specific
Scheme standard and thus work on all implementations supporting that
standard, there are few real world programs that can be written within
such limits. And coming from a Common Lisp background, where the
standard is huge, you'll likely find the available Scheme standards
lacking.

I prefer to think of each Scheme implementation as its own distinct
language, because in many ways they are. I don't write Scheme
programs, I write Guile programs. I want to use Guile's delimited
continuations, foreign function interface, compiler tower, etc. so
limiting myself to standard Scheme would be a real bummer.
