Most people would leave this in.  I've no idea
what might break without it, but I'll wager something
might ... for example, what would you think of a box
that couldn't find "localhost" with both hands?  No lo,
that's what you might well get ....

"tun" is necessary for userland PPP.  If you
take out "tun", "ppp", and "ether" as well
as SLIP, what protocols do you figure on
using?  Are you planning on connecting to
anything? (Note that I'm not saying there's
no other way, but these are so common ....)

I may be wrong, but wouldn't removing this
cause remote access (most of it, ftp, telnet,
ssh, etc.) to fail?

I suppose not if your disks are SCSI.

If no CDROM, or you have a SCSI CDROM, I guess not.

Most of your list is stuff that is generally standard
and fairly essential ... if you've minimized down this
far, I'd say you're getting close to small enough, wouldn't
you?
