Well, 99% of the times you can remove any reaction. The solution method would be different but the end result would be the same. Now, in this problem, you need to remove one of the horizontal ones otherwise your structure becomes a mechanism and can't be solve (try to remove a vertical reaction here and you will see). Good luck ;)
How do you know what forceto remove
