boot - Resize partitions Ubuntu 16.04 and Windows 10

I have a Dell Latitude 5580 and I reduced the factory Windows 10 partition by 15GB. Then I installed Ubuntu on those 15GB.

Now I want to increase the space by 10GB in my Linux. How can I do this safely with GParted live without damaging anything?

My GParted table looks like the attached picture.

When I tried to move the unallocated space I got a warning that changing this may alter my bootloader.

This is my current free space in Ubuntu:
