Yes and there are two options. First you can save the web form as submission-enabled PDF form and have the users fill out the PDF by emails in turn, the last one who fills out the form submit the form. The second option is to use the save web form data feature in FormsCentral. Users save their responses and pass on the links to next person who needs to fill out the form and then again the last person who fills the form submits the form.
