Yes. Suppose you enter

  x = 5;

and then have the following text cell

 Cell[TextData[{   
   "The value of ",   
   Cell[BoxData[FormBox["x", TraditionalForm]]],  
   " is ",  
   Cell[BoxData[FormBox["x", TraditionalForm]]],  
   "."}], 
 "Text"]

If you select the second x and do

   Kernel | Evaluation | Evaluate in Place

or use the keyboard shortcut, the value of x will be updated.

This process is, AFAIK, manual. There are, however, special objects that 
do update automatically, that can be created using

  Input | Create Automatic Numbering Object...
  Input | Create Value Display Object...

though such objects do not appear to function properly if they are 
inside inline formula cells.

Nor does there appear to be a way to automate the above process using 
"Create Value Display Object..." for the variable x, even after adding a 
CellTag to the defining cell.

Cheers,
Paul
