IIRC 'cascode' was a special configuration in
an amplifier (to my recollection, specifically
a low-level RF amplifier) and cascade simply
means 'A' follows 'B' in succession in a chain
of amplifiers.

From Skolnick, "Intro to RADAR Systems" dated 1962
pg 388 I find:

Cascode:

  "Grounded cathode triode followed by a grounded
   grid triode."

I suppose that the use of 'cascode' could apply
to solid state devices in similar configuration
where a higher-output Z stage (e.g. common or
grounded cathode) is loaded (followed by) a
lower-Z input stage (e.g. common or grounded grid)
could also be described as 'cascode'.
