Transformers such as the matcher appear to use hidden attributes to match on when the attribute matching strategy is set to match all attributes. Is it possible to remove hidden attributes without exposing them first?

You can use the BulkAttributeRemover.
Doesn't appear to let you remove any hidden attributes that start with fme_
You're right, it seems like the fme_* attributes enjoy some special protection by the BulkAttributeRemover.
Try this Python script in a PythonCaller instead:
import fmeobjects
def RemoveFMEAttributes(feature):
for attrib in feature.getAllAttributeNames():
if attrib.startswith('fme_'):
feature.removeAttribute(attrib)
Tested with FME 2017 and seems to do the job.

feature.removeAttrsWithPrefix('fme_')

Alternatively, the FMEFunctionCaller with this function call setting could also work fine.

...and don't forget about the "multi_reader_*" FME feature attributes, and the format-specific attributes like "geodb_*" for Esri Geodatabases. Also beware of the OBJECTID and SHAPE.LEN and SHAPE.AREA if they have been accidentally included in the User Attributes for some Esri formats.
