Is this fake Buddha quote synonymous with Buddhas quote in Dhammapada? Is this fake Buddha quote, 'Everything that has a beginning has an end', synonymous with Dhammapada verse, ‘All conditioned things are impermanent', the Buddha quote from the Dhammapada, verse 277?
If it's not synonymous, can somebody explain to me, how it's semantically different?
It is somewhat synonymous, just a bit simplified.
The original quote is:

yaṃ kiñci samudayadhammaṃ, sabbaṃ taṃ nirodhadhamman'ti
SN 35.74

or

&quot;whatever is samudaya-able -- all that is nirodha-able&quot;.

Samudaya means &quot;to come together&quot;, &quot;to arise from coincidence of multiple conditions&quot;. Nirodha means &quot;to stop&quot; or &quot;to arrest&quot;.
So the detailed meaning of the phrase is &quot;Whatever phenomenon emerges from the coincidence of multiple conditions, it will be no more when one of those necessary conditions is removed so it no longer contributes to the arising of the phenomenon.&quot;
Compare that with &quot;everything that has a beginning has an end&quot;. If you really think about it, the meaning is the same, but while the detailed analysis is very obvious in the original quote  it's rather hidden in the simplified one.
