Assuming you have provided your list of nodes as a cypher collection, would this do the job?

MATCH path=(start)-[r:*1..100]-(end)
WHERE ANY(node_on_path in NODES(path) 
  WHERE node_on_path IN node_collection)

You may also try using a list of values against which the nodes on the path are checked, something like

MATCH path=(start)-[r:1..100]-(end)
WHERE ANY(node_on_path in NODES(path)
  WHERE node_on_path.some_property IN list_of_acceptable_values)
