Not at this time. Apparently, support for the front camera was specifically removed from the Flash plug-in in Maemo 5 for privacy reasons. See bug 1889.

You may vote for bug 1889, if the issue is important to you; however, as the bug has been redirected to Brainstorm, votes on it in Bugzilla aren't as visible as they once were. I've no idea if a Brainstorm for the issue was ever created.
