trimming

I want to put some trim along the top of tuis stringer, but this part has 3 sections and it would look better and be easier if I reduced it to two sections. Is it safe to trim the part above the green tape off the top of the stringer? It would be up to 8mm at most.

Hi all, I feel this is something of a dim question, but bear with me... I have a selection of trees that I trim periodically, I have been using an old hedge trimmer that I had from a previous house for this, it's okay, struggles a bit on thicker branches and doesn't quite have a long enough...
