Are the Duplo Journal Reader and the AS/400 Journal Reader the same thing?

No, to the AS/400 Journal Reader is an own process of the operating system, which captures changes, while the Duplo Journal Reader is the element that processes the changes captured by the trigger or, indeed, by the Journal Reader, in the case of AS/400.

Is it possible to use the Reader Journal on AS/400?

If you want to use the capture mode of changes by Journal Reader, you must perform an additional configuration step. Duplo has the possibility to synchronize in AS/400 differents environments. The system's name is a three-byte ID that identifies the environment that you want to synchronize which appears in the first three bytes of the job's name. The last three bytes of the job's name identifies instance operative Journal Reader. Within an environment, you can submit more Journal Readers. In the typical configuration, the AS / 400 is seen as the only synchronization environment, where we can just have a Journal Reader for journal operative.

Does Duplo work on Linux?

Duplo runs in background, taking control of the console. If closed, terminate would be the process of Duplo. To ensure that this process is not tied to a console, it's necessary to make sure that Duplo is run as a "daemon", in other words a background process related to corrent execution's runlevel. Duplo, therefore, depends on the operating system, is started when you start the system, and is stopped when the machine is turned off or rebooted.
