No... you'd leave 2018 and be in 2010 again with your past self being there too, but once you return to the future = whatever changes you've done in the past could alter you and your future life upon your return from it. So changing the past could ruin your future time if you keep messing around even in the slightest, but any good done like Okabe saving Kurisu in that way while still preserving the worldline events as they were could have better results later.

Like Okabe said many times before: messing around with time and altering it is extremely dangerous for all of us and everything we hold dear + love in life as its all put into risk on a thin line of fate... its better off that we leave it all alone and not alter it in the slightest unless the end of the world was to occur + that we know about all that will happen and how to change as well as stop it in the past altogether with someone like Okabe and Suzuha together with the knowledge and plan at hand on how to fix everything.

Its just absolutely horrible... you don't want someone to mess up the worldline for all of us in such a way beyond repair = only to realize later that you accidently dropped a future tech in the past that Hitler found in his early life and used it to help him win WW2 and our world turns out later in looking like Mars by the time of our present day when waking up do you? I certainly don't want that to happen nor anything like we see with future Sern or WW3.

Long story short: keep the machine on ice = hidden and on standby ready in secret just in case until something really bad happens in the near or far off future that forces you without no choice secretly in using it to save the world or gathering others to help you do so altogether that makes it easier than just Okabe doing all of it himself with Suzuha's machine.
