[Star Wars] Do the 90s Thrawn books still fit the timeline of the 2017 reboot?

Hello! 

I just started reading Thrawn (2017) and realized there are 3 previous books that are now Legends from the 90s by the same author. 

I understand that these are no longer *canon*, but if I were to choose to read them after Thrawn, Thrawn: Alliances, and Thrawn: Treason would their story make sense and still fit the later timeline or is anything directly contradictory? 

I am still very early in the books, so a non-spoiler answer would be greatly appreciated. (I'm also not sure if 'reboot' is the correct term so apologies there).

There's a ton of stuff that doesn't line up or fit anymore. While the broad strokes aren't going to contradict each other all the minor details that build the story will. The clone wars in 90's legends were vastly different. Thrawn himself is a little goofier but still a great character. Several very important figures are dead in canon or never existed in legends. And the era that heir of the empire and the other two takes place in is radically different than the one in canon.
