I still think that Python/CPython is a good example, it shows how confusing
can it be when the reference implementation and the language has a
different name:
http://stackoverflow.com/questions/17130975/python-vs-cpython
As Zeev mentioned the CPython name is mostly just used for to refer to the
vanilla implementation when comparing to others, but the codebase of it
still refer to itself as python.
I think the only case when you can have a separate name for the reference
implementation than the name of the language is at the start, if you do it
anytime later, it will cause some headaches, but it isn't impossible as we
can see from the python example.

Ruby is also an interesting example, there are also a bunch of alternative
implementations, the reference implementation refers to itself as ruby, and
when comparing it to other implementations it is either called MRI (Matz's
Ruby Interpreter) or CRuby.
