My opinion is that with limited budget it's always better to go for a desktop rig because a gaming laptop is always way more expensive.
I've taken a look at the tech specs of the Lenovo:

I have a few issues with it.
1) Unless you are able to get the GT 755M SLI version, the single GT 755M is CRAP. I'm serious. I had a free Alienware 14 given to me, it came with the GT 750M which is slightly, really slightly behind the GT 755M. You can never run high settings on full HD with that, it gives you really crappy frame rates and performance and stresses the GPU a lot. I was in Japan during 2.2 launch and that was the only gaming laptop I had and I had to make do with low settings to get some acceptable game play. But low settings doesn't bother you then yes, GT 755M can produce 30-45 FPS on low settings, at 1080p full screen.
2) It runs on a... wait what, 5400rpm HDD? What again. 5400rpm, you kidding me? Most people are actually using SSDs these days for faster load times. I haven't been using a HDD for years but I have friends telling me the load times for FF14 ARR differs quite significantly on a 7200rpm HDD vs a Samsung EVO SSD. And a 7200rpm HDD is really a bare minimum for a gaming laptop. IDK why the crap Lenovo puts a 5400rpm there.
For a smooth and enjoyable FF14 ARR experience on 1080p I would recommend you to look at at least:
4th Gen Intel® Core™ i7-4700MQ (like 90% of the gaming laptops are on this, so not an issue finding one)
GTX 765M and above (for high settings on full HD). The replacement model is GTX 860M but GTX 765M is still good to go
Samsung EVO SSD 120GB for OS and prog/game installation
16GB RAM
Look into the chassis design especially heat sinks and how it dissipates heat. Some designs are so terrible that heat causes the machine to get sluggish and wasted any good hardware installed.
