Sure they can coexist. By that I mean that they both can be loaded into apache and serve different things.
You can use mod_jk to parse jsp pages or servlets by a tomcat server and mod_proxy to proxy some backend server. Note that the backend server is not necessarily the same tomcat. It can be a different tomcat or a complete different server (like a webmail server).
What I don't think is correct, is to use both modules to parse the same URI. E.g. something like that:
JkMount /foo/* ajp13
ProxyPass /foo/ http://tomcat.server:8080/foo/
