No.

Do not run fsck on a live or mounted file system. fsck is used to check and optionally repair a Linux file systems. Running fsck on a mounted filesystem can usually result in disk and/or data corruption.

This will force a check on next boot:

sudo touch /forcefsck

So will this but it will also reboot the machine at the moment you hit enter:

shutdown -rF now

There are more ways (like telling the machine to go to init 1 and then umount the partition/disc your want to check) but these 2 are the easiest.
