Yes, this is what the Platform and JDT wizards are doing. We start out with an INFO rather than ERROR status. Finish and Next would be disabled of course. If the user enters something and then clears again, you would show an ERROR status.

If your wizard uses data binding, org.eclipse.jface.databinding.wizard.WizardPageSupport does all that special handling for you. See also org.eclipse.jface.examples.databinding.snippets.Snippet014WizardDialog in org.eclipse.jface.examples.databinding.
