According to our friend Clive,
http://www.davros.org/rail/culg/northern.html
says that services between Clapham Common and Morden were inaugurated
in 1926.
IIRC there were tunnels in the King William Street area, of a size
for Tube
stock in the 1890s (I may be very wrong on this), so the tunnelling
equipment
itself may not have been an issue.

King William Street to Stockwell was opened in 1890


Checking this site,
http://www.btinternet.com/~ptaffs/pe.../personal.html,
shows that Morden is located near a narrower portion of the Thames,
which meant
that sending tunnels under the riverbed would have been a bit easier
due to
simply having less water to worry about.

I'm not sure how that has any relevance. Neither of the two Northern Line
crossings of the Thames is anywhere near Morden.

The parent poster was asking about whether or not the primitive tunnel-digging
technology of the early 20th century was what prevented the LUL engineers of
the day from digging tunnels beneath the Thames and building Tube stations
south of the river. IMVHO Morden's location is irrelevant; what is relevant
is that it wasn't opened until 1926 - approx. thirty years after the first
LUL tunnels were ever dug, which meant that the technology had time to improve.
