Yes, there's a chance you can do that.  It should be as simple as removing
the old one, inserting a new one then making sure it boots up properly and
error free.
You could also just reseat MSM-B, in my experience this has fixed more
than a few problems.

An even better indication that MSM-B has failed outright then.

You can still log a case with Extreme, I think the cost is $500 USD per
incident.  They will just suggest the same things I am though, remove the
MSM, reinsert it, exchange it etc.  All carry a risk the BD will crash and
need a reboot.

Of course, so I'd schedule an emergency outage on it for a couple of
hours, get someone on the phone with some Extreme experience, get a spare
MSM, cross your fingers and pray.

Just make sure you backup the config via TFTP first of all before you do
anything.

Hope this helps you in some way.
