Yes its possible, however its probably not a very good way to speed up your
wiki and it probably would not be much faster.

For the use case you describe, id reccomend setting up varnish (ideally on
a separate server) in front of your wiki. There should be instructions on
how to do this on mediawiki.org. anyone not logged in will be handled by
varnish which will be faster than mediawiki. However thats not an option on
a free shared host

If varnish is not an option, use file cache which is basically a crappy
version of varnish.

Other notes about your config:

Make sure the cache directory is writable by the webserver

$wgMainCacheType should be set to CACHE_ACCEL. This will make your wiki
significantly faster and is one of the most important things you can do.
(Assuming apcu is set up correctly)

wgUseLocalMessageCache should probably be false. You already are using
cache_accel for it, that setting probably just means its stored twice.

You should also ensure apcu.shm_size is large enough (aim for at least 64
mb. Maybe more im not really sure)
