Allow Deletion of Selected Data Series from the Chart Legend (But Not from the Chart)
Prior to Excel 2016, it was possible to delete a data series from the chart legend without deleting the data series from the chart itself. (The user just double-clicked on the data series name in the legend, and then hit “delete”.) This legend editing feature is useful in charts which contain data series which are not the focus of the chart (for example, chart annotations which are plotted as a data series). Without this legend editing feature, the legend can become unwieldy. Please restore this legend editing feature to Excel.

It is two single clicks, not a double click, that selects a single legend entry. Once selected, the entry can be deleted.

That is excellent news!
I just checked this in Excel 2016 RTM. It works as you describe it. I can double click on legend labels and remove them without affecting the chart itself.
