If you loosely follow the definition of social media to mean “Website where you can interact with people in any way” then yes.
But I think the average colloquial use of the term social media really refers to websites where you make a real life personal profile and share things on that profile. Facebook, Instagram, Twitter, etc. You as the individual are the focus of those types of sites.
The (original at least) point of sites like Lemmy and Reddit is sharing information where you as an individual are not the focus. Hence posting to communities rather than your own wall or profile, the use of usernames over real names etc.
