According to Microsoft, you can now remove individual items in the recent search list in Windows Search by clicking the “x” that shows when you hover your mouse over the items.

You'll be able to turn this feature off if you don't like it. Simply click Search history on this device under Settings, Search, and Permissions and History. Please be aware, though that if you’ve not used Windows Search Box before and have 0 recent items, the recent list will be hidden.
