all counter melody is counterpoint, but not all counterpoint is counter melody.
counterpoint can be rhythmic, harmonic, melodic or textural etc.
classical music theory, 'counterpoint' has strong designations in referring particularly
to system of composition used in the Renaissance and Baroque eras, so you have
"Renaissance counterpoint" and "baroque counterpoint" as actual styles of music
If you were studying counterpoint in a music degree it is quite
likely you would be writing fugues in the style of Bach(baroque era), or making polyphonic
vocal pieces in the style of Palestrina (Renaissance) etc.

Quote 10ndaYii: how is
counterpoint different from counter melody
Whenever two or more instruments play, not in unison, there is
counterpoint. When no attention is paid to whether each part has a coherent musical line
(as in a badly-harmonised hymn tune, where the lower voices are merely filling in the
harmony) it's bad counterpoint. When one instrument has a line of comparable interest to
the melody, and is scored in a way that lets it be heard with equal prominence, it could
be called a "counter-melody". You could even have more than one counter-melody (Wagner
has a good example in his overture to "Meistersinger") though it's arguable that combining
more than two prominent melodies can easily become merely confusing.
"melody counter melody" for more opinion and examples.
