Is there a difference?

Both meanings are identical. The only difference is in formality, with the apostrophe version being slightly less formal, and thus not appropriate for some contexts.
in "Our school rugby team is good", "school" is a noun adjunct. Essentially we are no longer discussing [rugby team]s but instead [school rugby team]s. Just as the term "rugby" in "rugby teams" narrows the scope from all possible teams to only those focused on rugby, the inclusion of the term "school" narrows the scope from all possible rugby teams to only those based in schools. the "our" is the possessive.
In "Our school's rugby team is good", "our school's" is the possessive and [rugby team]s is the scope.
So the former implies that schools having rugby teams is prevalent enough to place them in their own category while the latter implies only that the school has a rugby team without implying that this is the norm
