You can try the TagTransform plugin:
http://wiki.openstreetmap.org/wiki/Osmosis/TagTransform

A translation along the lines of this should drop entities not
matching the regex:

<translation>
   <name>Drop</name>
   <description>Drop without mykey</description>
   <match>
     <notag k="mykey" v=".*"/>
   </match>
   <!-- no output description means matching entities are dropped -->
</translation>
