No, it's a fully custom CPU architecture and implementation, though they could use a 68020 as the "LX" co-processor. Also their primary competitor Symbolics used two 68000s in addition to their custom CPU: one as an I/O and boot controller, another as the heart of their console i.e. a graphical terminal.
