Nope. As most things shell it (rightly) ignores the whitespace.
Take a look at this little script to prove it to yourself:
#!/bin/sh
VAR=foo
case $VAR in
foo )
echo "I don't care about whitespace"
;;
foo)
echo "OOoops, guess I do"
;;
esac
VAR='foo '
case $VAR in
foo )
echo "D'oh! I see the whitespace in the variable"
;;
foo)
echo "D'oh! I don't see the whitespace in the variable"
;;
'foo ' )
echo "I see what I am supposed to see"
;;
esac
