Maybe. More likely there are more digits, like 2116, 2114, 2115,
2100, 21MX, 21xx....

Most of the HP1000 CPUs have 21xx numbers as well. The 1000 line was,
originally, a bundle of a 2100-family computer with HP's RTE real-time
executive; eventually HP silk-screened "1000" on the front instead of
"21MX", but the actual model number of the processor (the tag on the
back) was still 21xx.

There were also the HP2000 time-shared BASIC systems, built out of
one or two 2100-family processors.

2100-family processors also found their way into all sorts of big HP
test and measurement systems in the very late 1960s and 1970s. For
example (note these URLs are *temporary*):

HP2116 looks like, and underneath that would appear to be a drawer, a
filler panel, a paper tape reader, and a paper tape punch.

you can use your editors too....)
