[Warhammer 40k] Could a Space Marine survive reentry into Earth?

Would they burn up and if they survived that would they live past the landing?

No.  
A) There is reason they use drop pod.  
And More Importantly.  
B) Vulcan the Primarch of Salamanders did Die reentering Atmosphere. He did get better.  
So if Primarch Die from Reentering SMs will definitely do so.
