Basically, the answer to your question is no for multiple reasons. Inside Tress, they are definitely not centuries in the future. Inside Tress, Hoid mentioned at one point that it had only been a few decades after Sazed released the Kandra. This being around probably 30 years after Wax and Wayne. Also, this is still before Mistborn era 3. And Sanderson mentioned that the 3rd Mistborn era would be like 1980s to 90s time period, so they would not be doing space travel quite like that (though that might be possible if using etmetal). Also, the spores on Lumar have likely been there for centuries if not the beginning of the world, or at least since the moons were inhabited by aethers. I actually wouldn't be surprised if everyone there is actually descendants of people from off-world. Though this is not centuries in the future and there is no Scadriall interstellar empire there is a chance this might exist in Mistborn era 4. Especially considering the fact that Scadrial is likely the oldest world, and they have two merged shards that kinda help and influence them.
