Yes, Illinois law permits a joint tenant to mortgage his interest in property without the other joint tenant's consent or knowledge. However, the lien does not sever joint tenancy. In other words, upon the mortgagor’s death, the lien is extinguished, and the surviving joint tenants will take their interest free of that encumbrance.

Where a cotenant who owns less than the entire interest attempts to mortgage the whole, the mortgage is valid as to the actual interest of the mortgagor.”) (internal citations omitted)

While [the co-tenant] was alive, the mortgage existed as a lien on his interest in the joint tenancy. Upon his death, his interest ceased to exist and along with it the lien of the mortgage.”)
