Is "X" here a "synthetic" register, so may I replace it with any numeric one?
No. X, Y, Z and T (and also L = LastX, for that matter) simply are the usual stack registers. Yes, the '41 can also use the stack for commands like DSE, ISG, STO, RCL, X<>, VIEW and others. It is not limited to the regular numbered standard registers.
If you use these commands, the stack registers can be addressed by pressing the decimal point [.] before X, Y, Z, T or L. At this point, the '41 shows a "ST" to indicate that you are about to use a STack register.
[XEQ] [ALPHA] D S E [ALPHA]
=> DSE _ _
[.]
=> DSE ST _
X
=> DSE X ; as usual, the X is on the "6" key

Is it possible to enter function name into program from Catalogue directly?
No. At least not with a standard '41.
