Yes, timestamps can be forged.

If someone was careful enough and had plenty of fakes nodes, they could fabricate such a thing.

But what about the difficulty of the proof of work, considering it is high, wouldn't it require massive amount of computer power to fabricate it ?

All paid signature campaigns should be banned.
Why are you beating all around the bush?  Which alt are you talking about?

Could it be possible to fabricate a presumably 2 years old blockchain in less time (or even instantly) ?

Recently a coin has appeared that claims to be launched two years ago, however, no evidence can be find about it but the blockchain with the actual timestamps.
So I am asking, is it possible to manufacture a blockchain that appears 2 years old but has been recently forged ? The chain has the difficulty and cumulative difficulty values, so I gues this could be possibly checked.

The blockchain in question uses the same concept as Bitcoin (the same byzantine generals solution) but with a different implementation and different PoW.
