...maybe, plus it has sockets to charge your phone etc. At 422g boxed the Anker unit looks rather heavier than the Lenovo 45W travel adaptor (320g boxed, 190g weight) though, plus one of the Q&A answers suggests it charges at 30W so might not be as fast. I like the USB type A sockets though - handy if you want to charge your phone at a hotel at night without unpacking your laptop.
For those in UK the QuickPick link is http://www.lenovoquickpick.com/gbr/system/thinkpad/x-series/x1-carbon-5th-gen/20hr#category/6 - I can't see a 65W travel adaptor, but the regular 65W adaptor is 222g, boxed 460g (https://download.lenovo.com/pccbbs/options_iso/65w_std_acadapter_usbc_4x20m26268.pdf), so possibly not much heavier than a travel version.
BTW I had a related quesion about RapidCharge here if anyone has ideas: Reducing the charging rate for an X1 Carbon

I read this article when browsing around: https://www.theregister.co.uk/2016/08/30/anker_usbc_cables_recalled/
I hadn't really considered how the power was being transmitted with USB-C (though have already started worrying about the long-term wear characteristics of such a small connector) but this makes me think it is probably best to stick with Lenovo chargers/cables, at least for now.
I can't help feeling I will need to buy a powerbank though for long haul flights, plus have always wanted a charging cable with a power indicator light... hopefully as USB-C charging matures such issues like the above will disappear.
