The relationship between the arguments in Tractatus and Philosophical Investigations (PI) is quite complex and, while there is some disagreement over the the degree of his renunciation, it's generally understood that by the time of his writing much of the notebooks that ended up as PI Wittgenstein had altered his understanding of philosophy and language quite a bit.

Both had a sort of "end philosophy" ambition, to a degree. The Tractatus, with its ambition to address the ways that language touches the world in a picture theory, was more akin to the idea of "solving" philosophy in a sense. In PI, he makes a change in his view of philosophy towards anthropology and remarks on language that is rooted in behavior and use. PI "ends philosophy" more in the sense of dissolving philosophical issues, by revealing the conceptual underpinnings of a number of philosophical debates as nonsense. Philosophy's job, thus, becomes conceptual clarification.

So to answer your question, yes, though there is some overlap.

Well put, "Whereof one cannot speak, thereof one must be silent." is a call to cut through the crap of philosophy, rather than to end it. Whatever differences there may or may not have been, no one can deny they were both incredibly ambitious.
