Even if it did, it wouldn't matter. Time in Tensura exists in a branching manner, like DBZ. Actions to not change previous actions just create different timelines, for example, Manas: Chrona comes from a time outside of the current timeline, yet despite all the events that caused its creation changing, it still exists.

This shows that despite whatever the characters do to their past selves, it never effects the future they come frmo. Rimuru could return to his world and save his former self in the past, but it wouldn't change anything about himself, it would just create a universe where he died and one where he didn't.
