Did Newton know about that but refused to elaborate an explanation?

Clarification =the Units of the lamda constant is in terms of inverse distance ^2 which is 1/meters^2

Nope - Einstein created his cosmological constant in order to preserve the idea of a "static" universe, he felt that a changing (expanding or contracting) universe was unnatural as supported by his equations of gravity, so he created the constant specifically to maintain gravitational equilibrium through the universe as a whole.
Newton's big "G" is just a constant relating the strength of the (far field) gravitational force to the chosen set of units.
Also, I'm not quite sure which version of the cosmological constant you are citing, as genrally the constant that comes out of the metric goes as:
Cosmological Constant = 8(Pi)*(G)*(energy density)

Newton could have known nothing about it -- the mathematics involved is far hairier than anything Newton ever looked at. I do not know the physical dimensions of Einstein's cosmological constant, but if one knew that, one could do a dimensional analysis to see whether the formula you propose makes physical sense.

Did you know Newton's g. constant is not always constant? His proposal that it was universal is wrong. The physics trilogy determines at every solar mass has a gravitational energy value according to c2 = E/m. Check it out.
