#Yes you can break up the attacks from Two Weapon Fighting
The rules in the SRD make it clear that this is completely legal:
##Moving between Attacks
If you take an action that includes more than one weapon attack, you can break up your movement even further by moving between those attacks. For example, a fighter who can make two attacks with the Extra Attack feature and who has a speed of 25 feet could move 10 feet, make an attack, move 15 feet, and then attack again.
Clearly, Two-Weapon Fighting involves more than one weapon attack and thus qualifies to have those attacks broken up with movement in between if so desired.
If that isn't good enough, Jeremy Crawford (official D&D rules guru) has also made it clear that this is correct:
Can 2-weapon fighting bonus action/attack be split up with movement?...
Movement can happen not only before and after an action, but it can also happen between attacks.
Note: I realize this answer comes to the same conclusion as @LegendaryDude, but I felt that the answer would be much improved with the addition of cited sources.
