Once there is no Exim process running anymore, it is safe to remove/move
the queued files (there are two files per message, -H, and -D). In a
perfect world you'll move/remove the msglogs too.

Without deeper insight into how Exim works, this approach is safe. There
are some shortcuts possible, but this requires knowledge about the
inner workings (locked files, …)
If you want to operatate on a more abstract level (as the spool
hierarchy should be considered as a kind of black box to the avarage
operator), you can use Exim's named queues feature and move the messages
into an alternative queue using the Exim command line:
exim -MG hold ID...
later you can inspect this queue:
exim -qGhold -bp
and move the messages back
exim -qGhold -MG '' ID…

The queue runners that process your queued messages should not fail
totally if there is one "bad" messages, as they start at random messages
in your queue and should manage to empty the queue over the time, just
leaving the bad message there.
