I would like to update the Java version used by Mathmematica 10 from 1.7.x to 1.8.x/ Is it possible without installing Mathematica 11?
I have the latest Java on my system, but Mathematica 10 uses an old one.

You may use ReinstallJava with the CommandLine option.
ReinstallJava[CommandLine->"d:\\full\\path\\to\\java.exe"]
This information is not on ReinstallJava's documentation page but in the Calling Java from the Wolfram Language guide under the Launching the Java Runtime | Controlling the Command Used to Launch Java section.
Hope this helps.

$\begingroup$ @pnz Try calling
UninstallJavafirst. That might help. $\endgroup$ – Edmund Dec 16 '17 at 12:38
