Yup.
You probably want to use links with the -dump option, and redirect it to /dev/null. Here's how I run a db index daily:
30 1 * /usr/bin/links -dump http://localhost/updb.php?update=yes 1> /dev/null 2> ~/cron.errors
So at 1:30am daily, it grabs that page, throws any standard output to /dev/null and any errors go to a file cron.errors in my home directory.
Not sure if lynx has a dump option, but wget may work for what you are doing.
