2 revealing mistakes in season 4

Question: Before the future Admiral Janeway time-travels to cut time off Voyager's return trip to Earth, the time where she came from was stated as "10 years after a 23 year voyage across the galaxy", which would be 2404. But if the Star Trek reboot is canon, then the alternate reality is created in 2387. Would that affect anything?
Answer: It's been established that the reboot doesn't affect anything in the original timelines of any prior series. The alternate timeline of the new films does not change anything that came before.
