At some point the shoe's cleats will wear out but more importantly the screws that hold them in will get worn down to the point that a hex key or Phillips screw driver will barely be able to grab the screw.
The grease does two things: 1) it keeps galvanic corrosion and corrosion in general from attacking the screws' threads (ever get caught in the rain?), and 2) It helps the screw release easier if the screw head is worn down. Either way, you'll have to take the screws out. In short, yes, Lanocote should work fine for this job.
I've worn out probably 6 pairs of cleats out over the years. I always kept an eye on the condition of the screws because with my first pair I didn't, and I had a helluva time getting them out.
