Sort of. There are a few key points that can become problematic:
1. If someone's connected to the AP in the office (whatever), it'll
constantly try connecting if it's "in range". This can tie up the AP for
other people.
2. If it's just an AP for the office (e.g. there's a game-room or
laundry or other reason to specifically put wifi there), trying to
connect through exterior walls can be very hit-or-miss (metal-foil in
the insulation, efficient windows, etc all tend to block RF - I mean,
it's exactly the same reason you get fuzzy TV or radio if all you have
is the rabbit-ears...).
3. If it's just some generic "consumer" kit, it's really only going to
be able to handle ~2 dozen devices anyway (limited hardware resources)
4. People utilizing their phones as wifi hotspots that happen to collide
with the office AP, by virtue of being far enough away that they think
whichever channel is available; and creating local contention issues.
