[VFKD] Can I cut data cabe and reconnect in the future?

[besleen]

My plug (data steckdose) is in the far corner of the house and I can not get the best WIFI signals in the other rooms.
However, in the middle of the house (by chance), the main cable of my house is not under the wall.
I am planning to cut it and make a new "steckdose" there
In the future, If I want to leave the house can I simply reconnect it with a connector so that the new tenant can use the original plug?
I attached the picture of the main cable.
thanks in advance.
