I have a small webpage which shows me some information.
Is it possible to put it as tile into the windows 10 startmenu?
Two possible understanding of your question:
If you want to have a shortcut to the web page pinned to start menu - that is possible.
If you want to have information displayed on webpage to be shown on a dynamic live tile in start menu - that is not possible.
It can be done only if you write/create Windows metro app that parses the data from webpage and shows it on live tile.
