If I take the Magic Initiate feat and choose a different class's spell list, but pick a spell that's also on my class's spell list, can I cast it using my class's spell slots?

I have read this question and answer: Você pode lançar um feitiço de iniciação mágica usando slots de feitiço?

If a Druid takes the Magic Initiate feat, choosing the Cleric list, and takes a spell that's on both lists (such as Healing Word), can they cast that shared spell taken from the Cleric list with their class's spell slots?

The following leads me to think this is subtly different: the previous question dealt with a wizard taking a spell that was not a wizard spell. It was Not On His List. The Druid is taking a Druid spell off the Cleric list; it is still a Druid spell and available for the Druid to prepare.
