If you are asking whether you can make a nuclear warhead with a yield so small the you
could detonate it inside a room without destroying that room then the answer is no.
You could make an AM warhead any size you like, assuming you can manufacture the AM.
But a nuclear warhead requires a critical mass of nuclear materiel to be able to function.
It is possible (but illegal by international treaties) to make a so called 'micro' nuclear device
with a yield in the hundreds of tonnes of TNT range rather than the more normal thousands
to millions of tonnes of TNT.
Designs for such warheads were developed for the ORION project, a spacecraft propelled by
detonating nuclear warheads behind it and riding the shock waves.
But a full blown nuclear warhead that small isn't possible.
They do generate nuclear explosions in the 'lab' at a couple of facilities in the USA.
But they use giant machines to generate (by various methods) high enough temperatures and
pressures on a D-T target that it fusses into helium.
But they consume more energy than they output and are the size of a couple of football pitches.
