    Remove?

    You can do it if you REMOVE the two at top right corner.
    Are you saying to MOVE two; leaving them in the design somewhere?

    Hello, Wilmer!

    Yes, that's exactly what I mean . . . move two matches.
    . . Relocate them in the diagram.

    OK...

    move top middle horizontal match and first bottom horizontal match,
    use them to form a square (bottom 2nd column).
