Yes, but be careful to select "custom partitioning" during the install
and do think about how really you need such partitions (primary,
extended, etc). Once upon a time, the /boot had to be on the "lower
sectors"; it should not be an issue anymore.

Pure-linux multi-boot is very easy (actually I always have multi-boot
on desktops, to have space to try new things, not being stuck in case
of failures, test the whole distribution upgrades without breaking the
real thing, etc)

Well, what's the point with the various Linux'es? You have to repeat
yourself in the various settings (or be very clever on how you share
them, which IMO is a pain).
So, it is doable as it is on a single-boot machine.
