Yes, but not all partitions.
Switching to runlevel 1 stops many daemons and all users except root. This
allows to umount partitions such as /opt, /home, perhaps /usr, etc. But
the "/" can not be umounted, nor /lib, /var, /etc, etcetera.
So, yes, if you are going to do some maintenance jobs it is better to jump
to runlevel 1, but sometimes it is not enough.
On the other hand, it is also possible (I think) to remount a partition RO
to check it. After all, that is what the boot scripts do to check the "/"
during booting. The exception is "reiserfs": you really need to umount it
to repair. That's why now and then appear people with weird problems in
them (like unerasable unreachable files) and we tell them to fsck from the
rescue system.
HTH :-)
