Grub Menu Windows 10 boot manager not shown in Grub2 menu after Leap install

Win 10 installed with its standard partitions. EFI, MS reserved, C: , WinRE.
Before I shrink the C: partition, can I delete the WinRE partition?
It is always last in any PM I have used. I have read it ‘can’ be deleted, but recommended to keep it.

Thoughts? Before I get to putting Leap on again?

Thanks for the responses.
