If the rate of recession has sped up, then the linear model overestimates the closeness of the moon 4.5 billion years ago. Even with this overestimate it is still outside the Roche limit. So this does show that the moon's behavior is consistent with the accepted age of the earth.
Unfortunately, if the linear model overestimates the closeness of the moon 4.5 billion years ago then it wasn't at the Roche limit at that time. If the moon wasn't there at that time then it wasn't formed then, as most model seem to have that as its location of formation

If it was outside the Roche limit at hat time then this puts it at the Roche Limit (and its formation) somewhat earlier. If the moon was formed earlier than 4.5By by a collision with the earth then the earth would have had to exist prior to 4.5By. So, no it isn't consistent with the accepted age of the earth.
