With the partitions your single external hard drive should appear on
your desktop as two drives. You'll have to decide how much space to give
each partition. For example, if you have a 1TB drive you might break it
up into two 500GB partitions. The main issue is that TM does incremental
backups until whatever drive you give it is full. At that point it
prunes the oldest stuff to make room for newer stuff. In that way, how
far back in time you can go depends on how big the drive is relative to
how much stuff you need to back up. If you did back up both machines to
a single large partition it probably would work for a while but
eventually one backup would start getting starved for space as the other
used up space. Basically you would have two greedy processes not sharing
well together on the same drive. I have seen tricks where you use disk
utility to create a sparse image on the drive, mount that sparse image
and backup to that. The sparse image can has a cap set on how large it
can get so it would act like a partition, but at that point it might be
just as easy to make an actual partition.

The only way you'd be able to use the same HD, as far as I'm aware, is create a
separate partition. Then, name the partition's accordingly. Mac Mini as 1
partition, and MacBookPro as the other partition, as examples.
