It looks like it, yes. I have a test system I upgraded (zypper dup) to
42.3, it now also has grub2, although I don't need it. It doens't hurt
though.

Maybe yes, maybe no. I've got it on a W10 machine, and I ran into issues
when
I did that install (no big surprise there). I tried it when legacy grub was
obsoleted, but had issues with it finding all the instances on the machine
and
properly chainloading. I like the simplicity and granular control I get with
legacy grub or even easier, generic code and boot flag. Or maybe I've just
been too lazy to learn grub2 well enough to be able to easily do all the
things I can do with legacy. As I've gotten old I've become more obstinate.
:)

With an average of well in excess of 10 operating system installations per PC,
it's hard enough keeping track of what's installed where without having to also
keep track of how booting takes place or from what starting point. Generic MBR
code and Grub Legacy WFM, so get used for everything except OS/2, whose IBM BM
loads Grub Legacy on systems including OS/2. Typically that means a small
DOS/FAT on sda1, a duplicate FAT or slightly larger FAT, HPFS or EXT2 (up to
2000 MB) on sda2, EXT2 with Grub Legacy typically 400MB on sda3, and all non-DOS
operating systems, each with Grub Legacy on its /, on logicals. That includes
two PCs with Win10, e.g.:
