Yes.    I bought a couple diamond blades for my ancient B&D 7 1/4" saw
years ago.    They eat through block or old concrete.    They dissolve
if you hit re-rod.

mine is something like this-

The dust is horrific.   I've tried taping my shopvac nozzle where it
does the most good.   Works OK. . .sort of. .  .

But one time I got brave, plugged in to a GFCI outlet, and dribbled
water from a hose right where the blade meets the cement.      That's
a winner.  I doubt the water is as bad for the bearings as the dust
was-- but I'd use a 'sacrificial' saw for the job.    Get one at a
garage sale for $10.

Yes, a masonry blade will but a concrete block.  It will also generate a 
butt ton of highly abrasive dust, which will work wonders with your circular 
saw.

Wear a good particle mask and get a cheap circular saw.  Do it outside, 
where the wind will carry the dust somewhere away from mammals.

A little more controllable, perhaps, would be an angle grinder with a 
masonry blade.

I see mexicans doing this all the time for pavers, my neighbor had a
walk way put in, the dust made was a cloud 50ft x25x25, it was real
nasty and bad for the tool and people breathing it. Renting some sort
of wet saw is the only way to go.

I disagree & I've tried both.   The angle grinder gives less control,
won't cut as deep, and is just as dusty.  The up side is- you can
usually get an angle grinder for $12 at harbor freight- a saw will set
you back $30.

But speaking of HF---  anybody used the multitool to cut block?   That
should gain you control-- and have way less dust.

yes, i just did this yesterday with a 7" dewalt blade made for that 
purpose.  Made a window into a man door on a concrete block garage.

Some granite installers were putting in kitchen fancy stuff. Most all
was granite tops cut at the shop.

Watched the HMFIC, cut granite trim with a 4" angle grinder. A diamond
blade and by using a wet tile spong near the blade. The sponge trick
kept the dust down. It was a nice job from that crew. Some cuts have
to be done on the job.

A brick mason's hammer? I could cut a cinder block with one.

Even try a chisel and hammer.

(paraphrased)

Michelangelo? Why are you hammering that stone?

There's an Angel in there and I'm trying to get him out.

That's a skill I've never been able to acquire.   I have never done
much masonry- but can get by in a pinch.   I can break bricks and
blocks into smaller pieces-- but never have been able to get them to
break where I want them to.  [though I've learned that block can be
mortared back together fairly easily]

I've had a little better luck with an air-chisel.    But I still cut
them. . .  dust be damned.
