Yes LTE has provision of online charging via Gy interface. This interface exists between PGW/PCEF and OCS(online charging server). I don't know about legacy CAP based system.

And Vikram mentioned Gy can be used for the online charging interface. In Legacy system CAP/CAMEL protocol is used for the charging purpose and if a interworking/roaming is required between these two type of system then we will require some sort of inter-working function which will convert diameter signaling to CAP-SS7 signaling or vice-versa. Hope this answers your doubt.
