Not remotely close. Features of suspense titles usually equate to a feeling of nervousness, perhaps even a reluctance to turn that next corner. Having played my fair share of suspense titles (Dead Space series, Bioshock series, planning to play Amnesia soon, etc.), I know from experience that Metroid is in no way suspenseful. Even back when I first played only Nintendo consoles, I never felt that Metroid could be considered a suspense title.
Metroid has never made me feel the least bit uneasy. the hallway feel never felt all that real. I can't ever recall a moment where something jumped out at me and legitimately scared me; I was usually expecting it. This is speaking from minimal experience in Metroid, though. I've only played the original, the Prime series, and Other M. I would say the Prime series would be the best one that I've played thus far to have any form of suspense; third-person shooter, and platformer-style just don't mesh well with suspense.
And that's the issue with Metroid. If it were to try to achieve a feeling of suspense, it would be best to be in first-person, that way we'd see the scares firsthand. If we're angled as high as we were in Other M, any surprise would be lost, since the thing jumping out at you isn't inches away from your screen; it's only inches away from Samus.
The one thing though is I doubt Nintendo even wants Metroid to be a suspense title. Suspense titles are generally also in the horror genre, as there needs to be a bang with that feeling of suspense, otherwise that feeling is pointless. Indeed, that feeling of being alone can make it seem suspenseful, but I'm used to plenty of games where the main character is pretty much out and about by them self (Dead Space, anyone?). And then of course horror games usually have an M rating; not normal for a Nintendo title. A third party title, sure, but Metroid is straight up Nintendo.

With that logic, just about every game that you have done little to no research on is automatically a suspense title.
