Yes:
	alias	cd	'cd `xcd $cwd \!*`'

...where `xcd' is the following shell script, located somewhere in your
PATH.  (You may have to change the `cd' in the alias to `chdir'.)

#!/bin/sh
#
# alias cd 'cd `xcd $cwd \!*`'

case $# in
1)
	echo $HOME
	exit 0
	;;
2)
	case $2 in
	/*)
		echo "$2"
		exit 0
		;;

		;;

		echo "$1/$2"
		exit 0
	esac
esac

Try alias .. 'cd /$cwd:h' in your .cshrc, and then typing .. works.
This will work in csh or in tcsh.

But that doesn't deal nicely with `cd ../../foo/bar'...
Following is a solution that does _and_ is completely builtin!
Piece of cake right?  :-)

--------------------cut here--------------------
alias	cd	'set tmp=(\!*); eval cd$#tmp $cwd \!*/. ../ ~; echo $cwd'
alias	cd0	'chdir \!$'
alias	cd1	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval cd2 /\!^:h \!:2-:s-../--'\
		'|| chdir \!:2'
alias	cd2	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval cd2 /\!^:h \!:2*:s-../--'\
		'|| chdir \!^/\!:2'

Here's a slight improvement; check the output of `cd /'; furthermore
you won't get into trouble if you accidentally type `cd foo/ bar' or
if there is a subdirectory `0' and you type `cd0'.
--------------------cut here--------------------
alias	cd	'set tmp=(\!*); eval _cd_$#tmp $cwd \!*//. ../ ~; echo $cwd'
alias	_cd_0	'chdir \!$'
alias	_cd_1	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval _cd_x /\!^:h \!:2-:s-../--'\
		'|| chdir \!:2:h'
alias	_cd_x	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval _cd_x /\!^:h \!:2*:s-../--'\
		'|| chdir \!^/\!:2:h'
alias	pwd	'echo $cwd'

What do you do if your csh doesn't have eval and doesn't set cwd?
