I tried installing openSUSE on a 40GB windows 10 system (15GB used) and it decided to wipe windows completely, without additional notifications apart from the partitioning summary screen that says "remove /dev/sda1" ;-)
That sounds like a bug worth being reported.
What's the bug I should report? I think it is just working as designed. Someone decided on BTRFS as default. BTRFS can not reasonably be used on less than 40GB. (Personally, I would never ever put BTRFS on anything smaller than 100GB but that's a different story). The installer encounters a device with 40GB "disk size", fully occupied with windows10. The installer's preselected default is BTRFS. So there's no solution other than "wipe windows".
A nice feature would be "restart partitioning proposal with different parameters", as in: first change file system default from btrfs to xfs, then restart the automatic proposal generation. Maybe with rootfs on xfs or ext, anything over 10GB of space would be considered "good enough", so resizing windows would be a viable option with a 40GB disk.
